Pistol with a silencer - modern weapons

A pistol is a type of short-barreled weapon that is intended to fire at short distances. The first such devices were singly charged. Modern pistols are rifled, they have a three-dimensional shop.

In the explosion in the cartridge of the powder charge, a loud sound is produced, caused by the muzzle wave, with the powder gases emerging from the barrel after the bullet. In addition, the emitted charge is also far from silent. If the speed of the bullet exceeds 330 m / s, then it also creates an impact ballistic wave. To this, you can add sounds from the moving parts of the weapon.

This feature of pistols during shooting is often undesirable. For example, in battle, the loud sound of a shot can unmask or hunt down a game. The first devices to suppress such noise appeared in the late nineteenth century. And in the last century began their serial production.

However, soon in many states, restrictions were imposed on the acquisition of such devices, since they were often used by criminal groups.

A pistol with a silencer does not create a strong noise due to the reduction in speed and temperature of the muzzle. The simplest device for reducing sound is a nozzle with one or two expansion chambers, which are separated by transverse diaphragms. Its action is based on the expansion of powder gases even before their release into the atmosphere, due to which the noise is suppressed. However, the disadvantage of this device is that some of the gases are ahead of the bullet.

A modern pistol with a silencer can not only be almost noiseless, but also fire without a flame. Such weapons in the USSR began to be produced in the 1950s for security officers. It could be divided into two groups: for the army and for the KGB. In the second case, special ammunition was required. Pistols with a silencer for the army were created on the basis of Stechkin or Makarov. They were produced for military intelligence units and special forces. The basis for a noiseless PB was a Makarov pistol with a silencer. The device for eliminating the sound of a shot on this weapon was an integral, demountable, two-piece unit. This made it possible to remove the attachment of the silencer, and quickly install it before application. The PB inherited the shock-trigger mechanism from Makarov. The fuse was located on top of the bolt. When turned on, he pulled the trigger from the platoon automatically.

A pistol with a silencer is often used for combat purposes. Especially in the course of special operations, when shots should not produce noise or a flame. These types of weapons may be less effective than mini-machine guns or rifles, but they are suitable for concealed wearing. The pistol with a silencer "High Standard" is often used by intelligence and special forces of many countries due to its high accuracy of fire. The same can be said about the model Ruger MK22 LR. They have high accuracy of hit at a distance of up to 70 meters or more. Such pistols are in demand with many of the best special services in the world. In particular, they are used by Mossad agents and the Marine Seals division.
