Signal Makarov MP-371 pistol: technical characteristics, differences from combat

Based on the legendary Makarov pistol, known to many as PM, a Makarov MR-371 signal gun was created. Unlike its combat predecessor, which appeared in 1949, the Makarov MR-371 is a skillfully executed mock-up, the muzzle section of which can be equipped with a bushing-simulator if desired, and replacing the fake handle with an authentic one, taken from a combat model.

Where is the gun manufactured?

Signal Makarov MR-371 is an ideal copy of the combat weapon. It is produced at the Izhevsk Mechanical Plant. The model in almost all is analogous to combat PM - their details are identical, the pistols are equally disassembled and assembled, but differ in their purpose. The Makarov pistol MR-371 is not intended for combat fire, but for creating a noise effect. IzhMeh produces for him special ammunition - metal and disposable plastic cartridges, which only look very similar to live ammunition, but in fact they are noise. For the production of signal gun shells, weapon steel is used, which makes it possible and safe to further rework them for firing live ammunition.

Specifications

Separately to each gun produced at IzhMech, a passport and a certificate of compliance containing technical documentation are attached. The signal pistol is produced as a separate combat unit, it is completed with one magazine and a set of cartridges in the amount of 30 pieces. Upon purchase, a guarantee is issued for a period of up to two years.

• The shutter frame is movable;
• Descent - adjustable;
• The weapon is intended for a semi-automatic fire mode;

• For the manufacture of the case Makarov MR-371 used weapon steel, for the handle - plastic.

What makes the MR-371 different from the combat one?

The Makarov MR-371 signaling gun is different from its combat analogue by the lack of a "beard" on the shutter. In its place there is a small cut, which is intended to prevent the installation on the gate of criminal homemade products. Independent re-equipment of the shutter will lead to its destruction at the moment of the shot with injuries to the shooter.

Differences have touched and gun barrels. In the signal version, it is absent - instead of the barrel in the MP-371, a bar has been mounted, which has a longitudinal milling groove. The presence of a blind hole in the pin greatly reduces the fastening of the barrel, which complicates the process of altering the signal variant of the weapon under combat. In the barrel mounting there is inside the chrome-plated chamber, into which the cartridge is installed. To exit the powder gases in the front of the chamber there is a small hole with a diameter of 0.2 cm.

The Makarov MP-371 signaling gun is equipped with a limiter, which prevents the magazine from charging ammunition cartridges.

How does the weapon work?

The signal Makarov MR-371, in spite of the external similarity with the classic combat PM, as well as the similarity of the mechanisms, in work has several differences from the combat analogue.

The shooting from the signal pistol is carried out thanks to the self-cocking - after each shot it is necessary to carry out the cocking of the trigger and the fired simulator to be extracted with the help of a bolt from the chamber. Only after the platoon and ejection of the used imitator from the pistol mechanism does the new simulator enter the chamber from the magazine located in the handle. Thus, for each shot, it is necessary to press the trigger.

During the shooting of the MR-371 you can see the movement of the shutter, which makes it very similar to the combat PM. Shooting is carried out with the help of simulating cartridges and contained in them inflammable primers, designed to create a simulation shot.

MR-371: tuning

Makarov's pistol can be remade. It is enough to remove the handle from plastic and replace it with the same one from Bakelite used in combat PM and IZH-79. After working with the handle, the screw from the current PM can be mounted on the MR-371. You can also turn the screw yourself.

After replacing the handles and the screw on the signaling MR-371, you can also modify the stem of the imitation trunk, whose muzzle is painted red.

It is enough to wipe the paint with acetone. Elimination of the paint on the front end of the tube will give the muzzle a serious look, the signal gun will not differ from the combat or traumatic sample. The muzzle can be completely changed - remade under the slice from the combat PM. To do this, it is necessary to mount the PM-bushing into the standard one. The main thing is that the length of the bushing to be installed does not exceed 1.5 cm.

Cartridges

For the Makarov MR-371 signal pistols, special imitating cartridges are provided, outwardly very similar to real combat ones. The signal cartridges inside contain a container in which flammable primers are installed. Spreaders are the brands Zhevelo-N and KV-21.

For the production of signal cartridges, brass and plastic are used. Depending on the purpose of the shots produced, the owners of the weapons are selected the appropriate cartridges. To carry out the sound signal, plastic cartridges are used, and for reusable shooting - from brass. You can use them from -10 to +50 degrees.

Where is the MR-371 used?

The Makarov MR-371 signal pistol is a very effective means for self-defense. Since imitating cartridges with a shot create a strong noise effect. Signal pistols Makarova MR-371 due to external similarity with the combat analogue can perform psychological and overwhelming impact. The identity of its mechanism and spare parts with PM makes it possible to use the signaling MR-371 for primary and quite safe training in the possession of firearms. While assembling and disassembling the MR-371, it is possible to study the device and the mechanics of Makarov's combat pistols.

Advantages

To purchase the MR-371, you do not need permission from law enforcement agencies to carry and use firearms. This weapon is available to any user who wants to protect himself.

The MR-371 is simple and convenient to carry, use and maintain. With possible breakdowns to restore the normal functioning of the weapon, it will not be difficult to find the necessary components. Breakages in Makarov's signal pistols are rare. The long operational period of weapons is enhanced by the use of high-strength steel in production.

disadvantages

According to user feedback, for Makarov MP-371 pistols during long-term operation some drawbacks are characteristic.

They include a slight backlash of the shutter frame, which is the result of a strong pruning of the return spring in the factory production.

Occasionally there is a jamming of the mechanics. It occurs due to the accumulation of carbon and soot in the barrel or cartridge cartridges. To prevent wedging, owners should clean their weapons regularly after use.
