The PSS silent pistol or MSS "Vul" ("Вул") [1] is a Soviet silent pistol operating on a sealed cartridge system.
Operation
Cartridge
The PSS uses a specially developed 7.62×41 mm necked round SP-4 (СП-4), also used by the OTs-38 Stechkin silent revolver.[2]
The cartridge contains a propelling charge which drives an internal piston in contact with the base of the bullet.
On firing, the piston propels the bullet out of the barrel with enough energy to achieve an effective range of 25 meters.
At the end of its travel, the piston seals the cartridge neck, preventing noise, smoke, or blast from escaping.[3]
Action
The PSS is recoil-operated. It has a slide designed to operate silently, in keeping with the pistol's design for silent operation.
In other respects, the PSS generally follows traditional conventions, except for the slide's guide rod, which is located above the barrel and instead of guide rails on the pistol frame.
The weapon uses a special cartridge with an internal piston. It has been measured to produce a sound level of 122 dB.[4]
Variants
PSS-2
The PSS-2 silenced pistol was developed in Russia.
The PSS-2 is based on the original PSS but with some features of the SR-1M pistol and some improvements.
It fires the SP-16 noiseless 7.62×43 mm ammunition, more powerful than, but incompatible with, the original 7.62×41 mm cartridge.
Adoption
Developed around 1980 for assassinations and reconnaissance, the PSS was first issued to KGB Spetsnaz in 1983. It is under production in the special weapons foundry at TsNIITochMash. PSS pistols are still in use by some FSB and MVD units.
The PSS-2 was adopted by the Russian FSB security agency in 2011.[5] The PSS has also been used in the Syrian civil war.[6]
