This entry details Russia's PSS silent captive-piston handgun, as explained by Ian McCollum of Forgotten Weapons. It covers the unique SP-4 ammunition, the pistol's feeding mechanism, and its sound suppression capabilities, noting its sound profile is comparable to a suppressed .22 caliber firearm. The analysis highlights the mechanical compromises inherent in its design.
The PSS 'Silent' pistol, developed in the Soviet Union, utilizes unique captive piston ammunition (SP-4) to achieve internal suppression, eliminating muzzle flash and blast. Its design, featuring a sliding chamber and Makarov-derived controls, prioritizes covert operations for special forces and intelligence units. While effective, its deep grip and specialized ammunition present certain ergonomic and logistical considerations.
