Developed for clandestine operations in the soviet union during the 1980s, this pistol is very neat as it uses it’s own special 7.62x41 cartridge which features a self contained piston between the powder charge and the projectile, thus when fired all the gases and muzzle flash are contained inside the shell case as it is ejected, making it one of the quietest guns ever made even without a suppressor on the muzzle. It is in fact so quiet the loudest sound produced when firing it is from the action of the metal parts.
