Pistol with a silencer - modern weapons

The gun is a kind of short-barreledweapon, which is intended to fire at short distances. The first such devices were singly charged. Modern pistols are rifled, they have a three-dimensional shop.

When an explosion in the cartridge powder charge is hearda loud sound caused by a muzzle wave, with powder gases coming out of the trunk following a 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 a shock ballistic wave. To this, you can add sounds from moving parts of the weapon.

This feature of pistols when firing oftenis undesirable. For example, in battle, the loud sound of a shot can unmask or hunting a game. The first devices to suppress such noise appeared in the late nineteenth century. And in the last century, their serial production began.

However, soon many states imposed restrictions on the acquisition of such devices, as they were often taken up by criminal groups.

A pistol with a silencer does not create much noise fora reduction in the 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 they enter the atmosphere, due to which the noise is silenced. 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 onlybe almost noiseless, but also shoot 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 a given weapon was an integral, demountable, two-piece device. This made it possible to remove the attachment of the silencer, and quickly install it before application. PB inherited from Makarov shock-trigger mechanism. The fuse was located on top of the shutter. When turned on, he pulled the trigger from the platoon automatically.

A pistol with a silencer is often used in combatpurposes. 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 the "High Standard" silencer 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 a 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.
