The OTs-02 "Kiparis" submachine gun was developed by designer Afanasiev in the 1970s at the Tula Central Design Bureau for Sports and Hunting Weapons (TsKIB SOO) by order of the USSR Ministry of Defense. However, at that time, the subject of submachine guns did not receive development, and the design fell "on the shelf" until the early 1990s, when, by order of the Russian Ministry of Internal Affairs, work on submachine guns was resumed. In 1995, the OTs-02 "Kiparis" submachine gun was adopted by the Russian Ministry of Internal Affairs. Currently, it is used by law enforcement agencies of the Russian Federation.

The OTs-02 submachine gun is built on the basis of automatic blowback. Shooting is carried out from a closed shutter. The OTs-02 has a trigger mechanism that provides both automatic fire and single-shot fire. The fuse-translator of fire modes is located on the left side of the receiver, above the trigger guard. The receiver is made of stamped steel. OTs-02 is equipped with a shoulder rest that folds up and forward, and can also be equipped with a laser target designator and a removable muffler.

Submachine gun OTs-02 Kiparis (Russia)

Submachine gun OTs-02 Kiparis with folded stock

The OTs-02 submachine gun (TKB-0217) Kiparis was designed in 1972 by order of the USSR Ministry of Defense by the designers of the Tula Central Design Bureau of Sports and Hunting Weapons (TsKIB SOO) N.M. Afanasiev, N.V. Trukhachev and D.P. Pleshkov. The design of the famous Czech submachine gun Skorpion Vz.61 was taken as a basis. Nevertheless, the Tula submachine gun remained unclaimed at that time until the early 1990s. and an order for a compact submachine gun already from the Ministry of Internal Affairs of the Russian Federation. OTs-02 Kiparis was adopted by the Ministry of Internal Affairs in 1995 and is in service with Russian law enforcement agencies, including the FSO and the Federal Customs Service, to the present.

Automation submachine gun OTs-02 Kiparis works according to the scheme with a blowback. The trigger mechanism allows firing bursts and single shots from an open bolt. Shooting is carried out from a closed shutter. The trigger mechanism of the trigger type. The use in the design of a USM submachine gun of this type, instead of pricking the primer with a fixed bolt head when firing from the rear sear, allows for higher firing accuracy. The fuse translator is located above the trigger guard, on the left side of the receiver. When turned on, the fuse blocks the trigger mechanism and the shutter.

The receiver is made by stamping from sheet steel. The OTs-02 Kiparis submachine gun has a metal shoulder rest that folds up for more accurate shooting. The kit for the Cypress submachine gun may include a silencer and a laser designator. Sights consist of a front sight with a namushnik and an adjustable rear sight. The Cypress submachine gun is fed with cartridges from box magazines with a staggered arrangement of 10, 20 or 30 rounds and their output in two rows. Spent cartridges are ejected up and back.

The production of the OTs-02 Kiparis submachine gun turned out to be very expensive due to the large number of parts made by milling, unlike most modern samples of this type of weapon, including both foreign-made submachine guns and domestic ones, for example, the Kedr submachine gun. However, the OTs-02 at the same time is a high-quality, durable, simple in design and handling, very reliable weapon in operation, and its small dimensions make it possible to carry it hidden under outerwear.

Submachine guns

• Austria

The history of this type of small arms has a little more than one century, but its development does not stand still to this day. Even after the advent of automatic rifles, it has not lost its significance. In modern armies and special forces, firearms of this type are especially in demand. Russia is one of the first countries to pioneer the development of submachine guns, and a successful project in the field of creating new weapons of this kind can be considered a model called "Cypress".

Development

"Cypress" was designed in the era of developed socialism. The creation and refinement of weapons took place during the 70-80s. 20th century under the leadership of Tula gunsmiths headed by N.M. Afanasiev. They took as a basis the Czech submachine gun already developed at that time, but the craftsmen did not simply copy the sample, but carried out a deep redesign of the design, which led to the emergence of more advanced small arms. The completion of work on the creation of this prototype took place in the early 90s of the last century, however, after that it underwent many more upgrades.

Purpose of weapons

The submachine gun is intended for use by internal troops. Since it was more relevant for them with its simplicity, compactness and the ability to fire at moving objects at a short distance in different modes. For example, in settlements during special operations. At the same time, the weapon of this plan was created not to replace the main systems of automatic or individual weapons among law enforcement officers, but as a new universal addition to their equipment.

Application features

The Cypress comes with special ammunition, bullets fired from it give a lower chance of ricochet, which is of great importance when firing in confined spaces. Also, the possibility of using both of a different type and capacity was transferred from Scorpion. One of its main disadvantages is the inconvenience when hidden wearing under clothing. The handle has a sharp protrusion and every now and then tries to dig into the body. Therefore, in terms of camouflage, it seriously loses to both Western and other domestic developments. Although, if you choose the right wardrobe, this problem can be solved.

Options and additions

Cypress is a weapon of Russia, which was created for employees of special detachments and units of the Ministry of Internal Affairs, the complexion and additional units are presented in it in accordance with the requirements of these law enforcement agencies. Among the main indicators, in the first place is the noiselessness of firing, which the silencer perfectly copes with, under which its barrel was designed at the development stage. It is also important that the use of modern additional means of aimed shooting is provided for the installation of a laser sight, which provides undeniable advantages when used in shaded and smoky rooms.

Note to the table: striker - conical shape, reflectors - two; the numerator indicates the length of the weapon with the stock folded , the denominator - with the stock unfolded; the numerator indicates the height of the weapon with a magazine for 20 rounds, in the denominator - a magazine for 30 rounds; USM provides single and continuous types of fire; the fuse box is located on the receiver on the left.

Markings

On the body of the submachine gun, its parts and mechanisms, there is a marking, which is presented below:

findings

Summing up, we can conclude that the Kiparis software is a good small arms for combat in enclosed spaces in an urban environment and for special operations in populated areas. Possessing the ability to effectively use in terms of compactness, reliability, range and accuracy of fire, compatibility with modern aiming systems and the use of a silencer for silent shooting. As for the shortcomings, these are just small omissions of the designers. One way or another, experts still consider it the best among the created submachine guns in the entire history of this type of firearm in the modern history of Russia, and a worthy representative of its family among Western developments.

Incomplete disassembly of the OTs-02 "Cypress" submachine gun

Another submachine gun, also from the backlog of the 1970s, was the 9-mm OTs-2 "Kiparis", developed under the regular pistol cartridge 9x18 PM in TsKIB SOO (Tula) N.M. Afanasyev with the participation of V.K. Panfilov and D.M. Pleshkov.

Automation - based on the free shutter recoil. The barrel with the bolt box is pivotally connected to the body of the firing mechanism and leans down during disassembly. The percussion mechanism is trigger, assembled separately and removed entirely during disassembly, the shot is fired from the front sear. In the rear part of the body of the firing mechanism, a mechanical retarder of the rate of fire is mounted, which increases the stability and controllability of the weapon by reducing the rate.

The flag translator-fuse is located on the left and sets the modes of single and continuous (automatic) fire.

Lightweight metal stock folds up and down. When the cartridges in the store are used up, the protrusion of its feeder turns on the shutter stop.

Sector sight - with a drum (cam) like an APS pistol. The front sight is adjustable when shooting. Provision is made for fastening a laser target designator (LTD) and a silencer (SBS) without elastic elements.

A relatively long barrel for this class of submachine guns and a number of measures that increase stability during firing made it possible to achieve good accuracy indicators: when firing from a stop without a butt at a distance of 25 m, bullets of one burst fit into a circle with a radius of 67 mm, and the best half of the hits - 28 mm. With a butt, respectively - 64 and 22 mm. When firing in bursts, all bullets fall into a circle with a radius of about 100 mm.

"Kiparis" is a personal attack and defense weapon designed to engage targets with single and automatic fire in conditions requiring silent and flameless shooting. It is in service with the internal affairs bodies and units of the internal troops of the Ministry of Internal Affairs of Russia.

The Czech Scorpion was taken as the basis for the Cypress submachine gun. The design has been significantly improved. "Cypress" was created under a regular cartridge 9x18 mm according to the traditional scheme - with the magazine located in front of the trigger guard. Automation is based on the free shutter recoil. The barrel (resource - 6000 shots) with the bolt box is pivotally connected to the body of the firing mechanism and, when disassembled, leans down, opening the bolt.

The automation of the submachine gun works by using the recoil of a free shutter. Its trigger mechanism provides both single and automatic fire. Ammunition is fed from a box magazine located in front of the trigger guard. To increase stability when firing, a folding butt is used, which in the stowed position is superimposed on the receiver from above.

Description of large-caliber submachine guns

The open-type sight provides aimed shooting at a distance of up to 75 m. The submachine gun has a non-automatic fuse that blocks the trigger and the bolt. For shooting, 9-mm PM cartridges are used. A silencer can be mounted on the barrel of the submachine gun.

Shops are similar to "Klin", their capacity is 10, 20 and 30 rounds. When firing from a stop without a butt at a distance of 25 m, bullets of one burst fit into a circle with a radius of 67 mm, and most of the hits are 28 mm. In terms of ease of handling and accuracy of shooting, the Cypress is superior to the Klin. But "Cypress" has a lot of milled parts, so its production is more expensive than the "stamped" "Wedge". This was one of the reasons for adopting the Klin. As befits Russian weapons, "Klin" and "Kiparis" are reliable, easy to disassemble and clean. Height with magazine for 20 rounds -172 mm, for 30 rounds - 226 mm.

AEK-919K submachine gun

The 9 mm AEK 919K submachine gun is designed to suppress and destroy enemy manpower at ranges up to 100 m.

Product designation: "AEK 919K".

Scope: Armament of special units performing combat missions and ensuring the defeat and suppression of manpower.

A submachine gun is an automatic weapon in which the bore is locked, the shot is fired, the spent cartridge case is removed from the chamber and the cartridge case is deflected, the cartridge is fed from the magazine and the cartridge is sent into the chamber automatically.

The operation of automation is based on the use of the energy of powder gases acting through the bottom of the sleeve on a bolt that has no connection with the barrel (the principle of recoil of a free bolt). The shutter moves by inertia into a rollback, compressing the spring, removes the sleeve from the chamber, which is removed using a reflector. In the roll forward, the bolt captures the next cartridge from the magazine, sends it into the chamber and locks the bore with its mass.

The capsule is broken by a striker made on the bolt.

The trigger mechanism allows firing in automatic and single fire mode.

To conduct automatic fire, you must set the translator to the "" position.

In this case, the shooting will continue until the trigger is pulled or until the cartridges in the magazine are used up.

To conduct a single fire, it is necessary to set the translator to the "" position. In this case, when the trigger is pressed, only one shot occurs. To fire the next shot, release and pull the trigger again.

General arrangement and operation of submachine gun parts

The trigger box serves to connect all parts and mechanisms of the submachine gun.

The reload handle is used to cock the bolt, and is also a fuse against accidental firing.

The receiver is used to place in it the parts and mechanisms that ensure the operation of the submachine gun.

The movable parts are designed to feed the cartridge, lock the bore, fire a shot, reflect the cartridge case and consist of a bolt, an ejector, an ejector spring, a guide rod with a reciprocating mainspring and a rod reflector.

The barrel serves to direct the flight of a bullet; inside it has a channel with four polygonal rifling and a chamber made with two grooves to facilitate the chambering of the cartridge.

The magazine serves to place cartridges and feed them into the receiver to the chambering line.

The bushing is used to fasten the barrel and the receiver box with the trigger box. At the end of the sleeve, teeth are made that protect the sleeve from spontaneous unscrewing during firing.

A low-noise firing device (PMS) is used to reduce the sound level of firing.

Incomplete disassembly of the submachine gun

Disassembly of a submachine gun can be incomplete and complete:

- incomplete - for cleaning, lubricating and inspecting the submachine gun;

- full - for cleaning with severe contamination of the submachine gun, after being in the rain or in the snow and during repairs.

Excessively frequent disassembly of a submachine gun is harmful, as it accelerates the wear of parts and mechanisms.

The disassembly and assembly of the submachine gun is carried out on a table or a clean bedding; parts and mechanisms are laid in the order of disassembly, handle them carefully, do not put one part on top of another and do not apply excessive force and sharp blows.

Training in disassembly and assembly on combat submachine guns is allowed with special care in handling parts and mechanisms.

The order of incomplete disassembly of the submachine gun

1. Hold the weapon in a safe direction;

2. While holding the submachine gun by the handle, press the magazine latch and remove the magazine from the trigger box handle.

3. Before disassembling the submachine gun, you must make sure that there is no cartridge in the chamber, for which turn off the fuse, move the bolt back 20-30 cm using the reload handle, inspect the chamber. If there is a cartridge in the chamber, holding the bolt by the reloading handle in the retracted position, remove the cartridge from the chamber by shaking the submachine gun or by picking up the rim of the cartridge case with a screwdriver from the accessory

4. Pull the butt out of the receiver until it stops;

5. Turn the shoulder rest of the stock 180° down.

6. Holding on to the rods and at the same time pressing the button of the return mechanism, turn the butt plate up and remove the moving parts from the receiver;

7. Press the latch back and unscrew the threaded sleeve;

8.Separate the trunk;

9. Holding the trigger box by the handle, separate the receiver with a backward movement with your right hand;

10. Remove the reloading handle from the groove of the receiver.

Assembly procedure for a submachine gun after incomplete disassembly

1. Insert the reloading handle into the groove of the receiver so that the plug of the reloading handle is flush and without distortion with the front wall of the receiver sleeve;

2. Insert the receiver into the trigger box so that the threaded part of the coupling enters the hole in the front wall of the trigger box, and the bend of the bracket into the groove on the rear end of the trigger box;

3. Insert the barrel all the way into the landing hole of the receiver, orienting it along the flat on the shoulder of the barrel and the receiver sleeve;

4. Screw the threaded sleeve onto the receiver until it stops, while depressing the latch;

5. Holding the submachine gun by the handle and pressing the trigger, insert the moving parts and, sinking the return mechanism button, turn the butt plate so that the return mechanism button enters the butt plate hole;

7. Holding the submachine gun by the handle, insert the magazine into the trigger handle window so that the latch jumps over the magazine support ledge.

Submachine gun "Bizon"

The Bizon submachine gun was developed by the design team of the Izhmash plant, headed by V. M. Kalashnikov, the son of the famous designer of the AK assault rifle. The "Bizon" uses the principle of inertial locking and a trigger mechanism (which potentially increases the accuracy of the weapon) and has a number of unusual features.

America's top gun journalism professional P.D. Kocalis wrote, "The very first thing that catches the eye is what appears to be a grenade launcher mounted under a shortened AK." Indeed, "Bizon" has only 60 percent interchangeability with AK 101 series assault rifles.

This makes production cheaper. It is designed for a standard 9x18 mm Makarov pistol cartridge, as well as for a new high-impulse cartridge of the same caliber. And what makes Bizon similar to a grenade launcher is a unique auger-type magazine for 64 rounds (a multiple of 16, since PM rounds are stored in packs of 16 pieces). The Bizon store resembles the American-designed Calico store. The cartridges in it are oriented bullets forward and cannot be loaded incorrectly.

"Bizon" is a very light and compact weapon. With the butt folded, the length of the weapon is only 425 mm. With the butt folded out, the total length increases to 660 mm. The Bizon barrel has 4 right-hand grooves with a pitch of 240 mm. Muzzle device with large rectangular windows on each side, located above the center. It is ineffective as a flame arrester, but to a certain extent reduces the muzzle rise.

Its main purpose is to protect the muzzle and magazine from damage. The rear sight has two rectangular slots for shooting at 50 and 100 meters. The front sight is borrowed from the SVD sniper rifle. It has a cylindrical shape, at the lower end is a thread, it can be rotated with a special tool for vertical adjustment. One of the most interesting design features of the Bizon is the incomplete shutter recoil.

When this weapon is fired with a standard Makarov cartridge, the bolt does not reach the butt plate of the receiver. With these cartridges, the rate of fire is 700 rounds per minute. Makarov's high-pulse cartridge accelerates the bolt until it hits the butt plate of the receiver. As a result, the rate of fire reaches 650-680 rounds per minute.

Experts note the lightness and compactness of the Bizon, excellent applicability, low recoil impulse, rate of fire that allows you to control the length of the burst, quite acceptable accuracy and excellent hit probability. Most of the parts unified with the AK provide the "Bizon" with high efficiency in production. Its first samples appeared in units performing special tasks.

Tactical and technical characteristics:

Submachine gun PP-91 "Kedr"

The prototype was created by Evgeny Dragunov back in the early 70s, which is reflected in the name (KEDR - Design by Evgeny Dragunov). In 1994, the submachine gun was adopted by the Ministry of the Interior.

The weapon was designed for the 9x18 PM cartridge. Automation works by using the recoil energy of a free shutter. The receiver is rectangular, stamped. The 120 mm long barrel is rigidly mounted in the receiver, to which the pistol grip, magazine receiver and folding stock are attached.

A feature of the submachine gun is the modular design of units (parts), which provides for its incomplete disassembly without the use of tools: a magazine, a receiver cover, a return spring with a guide, a bolt, a trigger mechanism and a fuse-translator.

Hammer type hammer mechanism. The location of the trigger axis, the pins of the mainspring stop and the stop for the mainspring guide on the trigger are selected in such a way that at the end of the cocking of the trigger, the force of the mainspring creates a moment that causes the trigger to be pressed from the bolt. Due to this, a guaranteed clearance is created between the bolt and the trigger, eliminating the loss of friction in most of the work cycle.

The fuse translator blocks the trigger and pushes the shutter stop into a groove on the lower plane of the shutter, thereby preventing reloading when the fuse is on. The flag of the translator-fuse in this position partially extends into the hole for the index finger formed by the trigger guard, which allows you to determine the readiness of the weapon to fire in the dark by touch. With the middle position of the translator, single shooting is provided, in the extreme upper position - automatic.

After all the cartridges are used up, the magazine feeder raises the stop, which fixes the bolt in the rear position. A combined rear sight was used, which automatically switches when the butt is moved from traveling to combat position and vice versa. When the buttstock is folded up, the rear sight shield with a diopter rises, and when the butt is folded, a shield with a slot is raised. This ensures the convenience of aiming both when shooting from an outstretched arm, and with the butt resting on the shoulder.

Sights of open type. The front sight is mounted on the barrel at the front wall of the receiver, the rear sight is mounted on top of the hinged butt mount.

The weapon is distinguished by good accuracy both in single and automatic shooting. At a distance of 25 m, a circle with a radius of 5 mm can accommodate 100% of hits when firing single shots and 50% when firing in short bursts, which ensures guaranteed hitting of the target with the first shot (or first burst) at a close combat distance. Despite the relatively high rate of fire (up to 1004 rounds per minute), it provides shooting in short bursts of 3-4 shots.

A silencer and a laser designator can be mounted on the weapon.

The Kedr-2 submachine gun has a magazine in the pistol grip of the Uzi type, it is operated with one hand when firing, and a compensator brake is provided for stability.

Tactical and technical characteristics:

Submachine guns Degtyarev PPD-34 and PPD-40

PPD-34 is the first submachine gun adopted by the Red Army. Unlike the prototypes of various systems that preceded it, it was designed for a slightly modified 7.62-mm cartridge from an automatic Mauser system pistol. In favor of the choice of this cartridge was the fact that it was also used in the TT pistol adopted by the Red Army.

Thus, the supply of ammunition to the troops was simplified, and the production of barrels for both pistols and submachine guns could be carried out on the same technological equipment. The PPD-34 submachine gun is relatively simple in design. Its action is based on the use of the recoil energy of a free shutter when the barrel is stationary.

The pressure of the powder gases at the bottom of the sleeve gives the shutter the energy necessary to extract the spent cartridge case from the chamber, exit the shutter to its rearmost position and compress the return spring. The movement of the shutter to the forward position, the removal of the cartridge from the magazine and its introduction into the chamber is carried out by the action of a reciprocating mainspring. The trigger mechanism of the submachine gun provides firing with single shots and bursts. To switch the fire mode, the trigger mechanism has an appropriate translator. The submachine gun has a shock type percussion mechanism.

Cartridges are fed during firing from a detachable two-row sector magazine with a capacity of 25 rounds, which could be used as a handle when firing. Sights, consisting of an aiming bar with a collar and a front sight, are designed for firing at a range of 50 to 500 m. The submachine gun did not have a fuse as a separate part, but thanks to original design solutions, accidental shots were excluded.

PPD-34 was put into service in 1935 and was produced in small batches. Based on the results of its use in parts of the Red Army, it was modernized in 1938, during which the magazine attachment was improved and some changes were made to the production technology. The upgraded model had the designation PPD-34/38. The dismissive attitude of the generals of almost all the armies of the world (except Austria and Finland) to the submachine gun as a type of weapon was also manifested in the Red Army.

In February 1939, the People's Commissariat of Defense suggested that the country's leadership stop the production of PPD-34 submachine guns and withdraw them from the troops. The military motivated this proposal by the fact that, in their opinion, the submachine gun was an ineffective weapon and could only have limited use. As a result, submachine guns were handed over to warehouses, but their production was maintained to meet the needs of the NKVD border troops.

The attitude towards submachine guns changed dramatically during the Soviet-Finnish war of 1939-1940. Impressed by the actions of Finnish submachine gunners armed with Suomi submachine guns, the command of the Red Army not only activated all the PPD-34s stored in warehouses and manufactured back in the 1920s by Fedorov submachine guns, but also organized the delivery by aircraft to the front of the submachine guns that were available at the border guards. The production of submachine guns was transferred to three-shift work with the full use of all equipment.

At the beginning of 1940, another modernization of the PPD-34 submachine gun was carried out, which consisted in adapting it to use disk stores like the Finnish Suomi submachine gun. The modernization was carried out on the personal instructions of Stalin, despite the fact that the disks, although they can hold almost three times more cartridges, are bulky and inconvenient to use and very expensive and labor-intensive to manufacture.

The urgently developed disk magazine held 71 cartridges (two cartridges more than for the Suomi submachine gun) and was equipped with a cartridge feed mechanism powered by a special preloaded spring. Before the start of the production of modernized submachine guns, for some time disk magazines were produced with a special neck, which allowed them to be used in all previously produced submachine guns. For the modernized submachine gun, called "7.62-mm submachine gun of the Degtyarev system, model 1940

(PPD-40) "disk stores were produced without a neck, since it was equipped with a receiver consisting of front and rear stops used to mount the store. The front stop of the store was screwed onto the bolt box and fastened with a pin, and the back stop was attached to the bolt box with rivets In the groove of the front of the rear stop there was a spring-loaded latch that secured the magazine.

Like the previous model, the PPD-40 had an open sector-type sight, which provided aimed fire at a distance of up to 500 m, however, due to the low accuracy of automatic fire and the relatively low power of the pistol cartridge, firing single shots at a distance of up to 300 m and shooting in bursts at a distance of up to 200 m. The modernized PPD-40 submachine gun was put into production in February 1940 and was produced until it was replaced in production by the PPSh-41 submachine gun. In 1940, 81.1 thousand PPD-40s were produced, another 5.9 thousand pieces were manufactured in 1941.

Submachine gun Sudayev PPS-42

At field tests conducted from April 26 to May 12, 1942, A.I. Sudayev provided his submachine gun for the first time. In general, he passed the test, but the commission suggested that the designer refine a number of components, demanded the elimination of the failure of the shutter from the cocking during falls, strengthening the reflector and strengthening the fuse, reducing the size of the casing, changing the shape of the butt and a number of minor alterations that improve the manufacturing technology of individual parts.

The final field tests of submachine guns took place on July 9-13, 1942. The commission recognized the submachine gun designed by A.I. Sudaeva, the best of all the samples submitted to the competition, also noted that in terms of technological and combat qualities it significantly surpasses the submachine gun of the G.S. system. Shpagina arr. 1941 (PPSh-41). It was deemed necessary to urgently supply the submachine gun A.I. Sudayev for mass production in order to develop the technological process.

Automation of the submachine gun of the A.I. Sudayev 1942 is based on the principle of free shutter recoil. The length of the shutter is 160 mm, the diameter is 29 mm, the shape is cylindrical, the weight is 570 g. In the upper left part of the shutter from the back to a depth of 95 mm, a hole with a diameter of 9.5 mm is drilled for a reciprocating mainspring with a guide rod.

The shutter handle is located on the right. The trigger mechanism is designed for firing in bursts. Reflection of the spent cartridge case is carried out by a reflector rigidly fixed in the receiver. The trigger box is separated from the receiver, leans back. The fuse locks the bolt in the forward and rear positions.

The fuse handle is brought out of the fuse round, with a serrated surface, in the center of the head there is a through hole with a diameter of 5 mm. The handle is located on the right at the front of the trigger guard, but in some instances it is located in a special cutout in front of the trigger guard.

The length of the fuse handle is 28 mm, the diameter of the head is 13 mm. The casing is connected to the receiver by rivet and welding. The diameter of the casing behind the chamber is 33.5 mm, at the muzzle - 25.5 mm. There are 19 holes in the casing for air circulation, the hole diameter is 11 mm. The lower part of the casing, 20-13 mm wide, is open for the entire length of the casing.

The barrel is equipped with a muzzle brake compensator. Crossover sight for two distances. Fly with a fuse. Butt metal, folding, folded on the receiver. Stock length 245 mm. Shop carob type, detachable, adjoins the neck from below. The cheeks of the fire control handle are wooden. In the manufacture of submachine gun parts, stamping, welding, and riveting were widely used.

The 1943 submachine gun does not have a reflector rigidly fixed in the receiver. Its function is performed by the front part of the guide rod of the return spring. The reciprocating mainspring with a guide rod is located in the groove in the lower left part of the bolt body.

To strengthen the fastening of the reciprocating mainspring with a guide rod A.I. Sudayev developed an original detail - an emphasis of a reciprocating mainspring. It has the shape of a cylinder with a length of 28 mm and a diameter of 12 mm with a hole at one end for putting on a guide rod, while the other end is inserted into a through transverse hole in the bolt body 58 mm from its end. The barrel length has been shortened, the weight of the shutter has been reduced to 550 g.

The shape of the handle and head of the fuse handle has been changed and improved. Handle length 34 mm, diameter 23 mm. The handle is located to the right of the front of the trigger guard. Improved hinged butt mount. The butt latch head is placed above the receiver in its rear part. Reduced stock length to 230 mm. There are 20 round holes with a diameter of 14 mm in the casing for air circulation. The receiver and casing are one piece. The trigger mechanism, as in the 1942 model, allows only automatic fire (bursts).

Submachine gun Sudayev arr. 1943 received the widest use at the front in the landing and tank troops. It has become an indispensable weapon for scouts, skiers, partisans. The small size of the PPS made it very convenient and maneuverable when fighting in trenches, in dense forests, and in buildings. As for the lack of an interpreter for a single fire, the Soviet soldiers quickly became convinced in practice that, having trained, it is possible to fire from the PPS in small bursts (5-6 shots) and even shoot with single shots, releasing the trigger immediately after pressing it.

Submachine gun of the Sudayev system arr. 1943 in many respects surpassed foreign models of this type of weapon used during the Second World War. In particular, the MP-40 submachine gun, sung by the Nazis and in service with the Nazi troops since 1940 as the main model, was significantly inferior to the submachine gun A.I. Sudayev in many respects.

The MP-40 had an unreliable fuse, which often caused accidents. The slightest deviation from the cylindricality of the cartridge case, which often happened in wartime production conditions, caused failures during firing. The MP-40 magazine was very sensitive to contamination. Due to the lack of a casing on the MP-40 barrel, soldiers often received burns, so they often had to shoot with gloves on.

The MP-40 had a low muzzle velocity. In this regard, when firing at 200 m, it was required to exceed the aiming point above the target by 0.5 m, which made it difficult to hit the target. Due to the low rate of fire from the MP-40, fire farther than 125-130 m was not effective, and as for the mass of the weapon, its manufacturability and economy, the PPS-43 compares favorably with the MP-40.

PPS-43 was much lighter than the Degtyarev (PPD-40) and Shpagin (PPSh-41) submachine guns, both in the version with a disk and with a sector magazine (see table). Possessing excellent combat qualities, PPS was characterized by high manufacturability with a wide use of stamping and welding methods, which guaranteed ease of manufacture and rapid mastering of its production even in small factories equipped with pressing equipment no more than 50 tons.

PPS was also very economical to manufacture. So if 13.9 kg of metal and 7.3 machine-hours were spent on the manufacture of one PPSh, then 6.2 kg of metal and 2.7 machine-hours were required for the PPS, i.e. more than two times less metal and three times less machine hours were spent on the Sudayev submachine gun than on the Shpagin submachine gun. In the conditions of the Great Patriotic War, all the listed advantages of the teaching staff over other samples were of exceptional importance.

Submachine gun Shpagin PPSh-41

The widespread and successful combat use of submachine guns during the Soviet-Finnish war showed that this is a weapon that in the future, in the event of war, will be needed in greater quantities than any other. In this regard, the task arose to make it even cheaper, simpler and more portable.

In this regard, the designers were tasked with creating a new design for a pistol - a machine gun. At the same time, the task was set so that its details almost did not require machining, and in general the new sample should be so simple that, if necessary, its production could be mastered at any machine-building plant.

This task was brilliantly solved by a student of V. A. Degtyarev - a talented inventor and designer G. S. Shpagin, who at the beginning of 1940 began to develop a submachine gun, and in August he made a prototype and submitted it to factory tests.

PPSh-41 (Shpagin design submachine gun) was created in 1941 and then adopted by the Red Army. The PPSh-41 was a simple and cheap wartime weapon to manufacture, and was produced in significant quantities - in total, about 5 or 6 million PPSh-41s were produced during the war years. Shortly after the war, the PPSh-41 was withdrawn from service with the Soviet Army, but it was widely exported.

Technically, the PPSh is an automatic weapon operating on the principle of a free shutter. Fire is fired from the rear sear (from the open bolt). The drummer is fixedly mounted on the shutter mirror. The fire mode switch (single / automatic) is located inside the trigger guard, in front of the trigger, the safety is made in the form of a slider on the cocking handle and locks the bolt in the forward or rear position.

The bolt box and barrel casing are stamped from steel, the front part of the barrel casing protrudes forward beyond the muzzle and serves as a muzzle brake-compensator. The stock is wooden, most often made of birch.

Sights initially included a sector sight and a fixed front sight, later - a flip-over L-shaped rear sight with settings for 100 and 200 meters.

Early PPSh were equipped with drum magazines for 71 rounds from PPD-40, however, drum magazines were complicated and expensive to manufacture, not very reliable and convenient, and also required individual adjustment for weapons, so in 1942, carob (box) magazines for 35 cartridges.

The advantages of PPSh include a high effective firing range, simplicity and low cost. Among the shortcomings, it is worth noting the significant mass and dimensions, as well as the tendency to involuntary shots when falling on a hard surface.

PPSh-41 is one of the best small arms ever invented. At first glance, it looks rough, but in reality it is a very reliable weapon, shooting in almost any conditions. The first release of PPSh in July 1941 was mastered by the NKV plant of the USSR in the city of Zagorsk, Moscow Region, originally intended for the manufacture of PPDs. In October, due to the rapid advance of German troops to the capital, the plant was evacuated to the city of Vyatskiye Polyany, Kirov Region. Another plant that produced drum magazines for PPSh was also evacuated here from the village of Lopasnya near Moscow. G.S. Shpagin was appointed chief designer of this plant, which became the head plant for the production of PPSh for the Red Army. The Vyatskopolyansky machine-building plant worked very closely in cooperation with the Izhevsk metallurgical and machine-building plants, which provided it with metal, barrel blanks, the necessary tools and equipment. During the war, gunsmiths from Vyatskiye Polyany produced more than 2 million PPSh-41s.

In total, during the war, Muscovites produced more than 3.5 million Shpagin-designed submachine guns. In just four years of the war, the Soviet defense industry produced 5.4 million PPSh-41s.

After the 2nd World War, PPSh began to be supplied to many countries that were members of the Warsaw Pact, as well as to China, where it played a huge role in the campaign of millions of Chinese volunteers in Korea. Reliable and durable, these weapons have proven themselves in harsh climates and in the untrained hands of Chinese soldiers. In the 1980s, the PPSh was used by units of the Afghan people's police, and in 2004, according to some reports, it was used by the American occupiers during the "cleansing" of Fallujah, which once again confirms the reliability of Russian weapons.
