The PP-19 Bizon is a Russian made submachine gun distinguished by its high capacity helical magazine.
Developed according to specifications provided by the Interior Ministry (MVD), its design is based on the AK-74, and two thirds of its parts remain interchangeable with the AK-74. It operates exactly like the AK—anyone used to handling that popular weapon will find this gun extremely easy to wield. Its magazine holds sixty-four 9mm x 18 rounds in an unusual helical configuration. While the PP-19 Bizon has only moderate stopping power, its large magazine capacity cuts down on reloads.
