The PSS silent pistol or MSS "Vul" ("Вул") is a Soviethandgun that fires specially-designed subsonic 7.62×41 mm SP-4 cartridge. It was first issued to the KGBSpetsnaz in 1983. The weapon is compact just like the Makarov PM, and has a notably wide grip profile. The original PSS was succeeded by the PSS-2 in 2011, using the more powerful 7.62×43 mm SP-16.
