MSP Groza silent pistol
The MSP Groza ("thunderstorm") silent pistol is a double-barrel, derringer-type firearm designed in the Soviet Union in 1972.[1] The firearm is chambered for the silent 7.62×38 SP-3 cartridge which is fed via a two-round clip. The weapon was designed at the request of the special service. It is no longer in production, having been superseded by more modern designs.

Design
    
The Groza uses a specialised cartridge. When fired, an internal piston within the cartridge launches the bullet forward and retains all the gases within the case, thus making a near silent weapon with almost no flash.[2]
