PSS silent pistol
Soviet integrally suppressed firearm
The PSS silent pistol or MSS "Vul" ("Вул") [1] is the last completed weapon system resulting from the Soviet development of silent pistols operating on a sealed cartridge system. Two previous designs were considered unacceptable for use due to their limitation to two shots. Earlier systems included the MSP and SP-4M double-barreled pistols. 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 original PSS was succeeded by the PSS-2 in 2011, using the more powerful silent 7.62×43 mm SP-16 cartridge.[2]
