The barrel of a pistol for shooting cartridges equipped with elastic shells with non-lethal effect includes in breech section of cartridge chamber, after that a bushing with long opening formed through counter-long drilling to intersection of two long openings is installed, axis of one of those is eccentric with respect to the axis of the bushing in diameter direction, at that the inner inclined sections between the lugs are formed with the surfaces of cross section of instrumental openings at drilling, and the outer ones are formed with respective conical surfaces of instrument coaxially with respect to the channel of the barrel, besides that, the muzzle section of the barrel is arranged as a cylindrical narrowing with long slots and conical sections at the outlet and the inlet. After the cartridge chamber two cylindrical bushings are placed, the axles of the long openings of those coincide with the long axis of the barrel, at that the first bushing is fixed in the channel of the barrel with a pin pressed to the closed opening of the bushing arranged at the outer surface with cross boss, this forms in the bushing a concave surface with radial profile, and the second bushing has an opening the inner diameter of which is much smaller compared to the diameter of the missile, at that the inlet and the outlet sections of the bushing are arranged as rounded, behind the bushings the guide section of the barrel is placed, this has diameter somewhat smaller compared to the diameter of the missile, in the front section of the barrel the muzzle narrowing of cylinder type is provided, diameter of its opening is much smaller compared to the diameter of the missile, at that the guide section of the barrel goes to muzzle narrowing by cone-like transition section, and before the cone-lake transition section, on the guide section of the barrel, through cross openings are provided, besides that on the lower inner surface of the first bushing and on the outer surface of the barrel in front of the first bushing weakening grooves are provided, those promote destruction of the barrel at attempt of shot with cartridges with shell or lead bullets. |
