Also known as: PB, ПБ, 6П9, 6P9
The PB (ПБ, Пистолет Бесшумный "Silent Pistol") is a Soviet-designed integrally-suppressed Handgun introduced in 1967. Its design is based on the earlier 9×18mm Makarov PM. The Weapon features a quick-detachable additional Suppressor, a shorter slide, grip shell that covers the entire upper frame without rounded shape and a straighter trigger guard profile.
