The P-64 was the standard Polish military sidearm adopted in 1965 to replace the Soviet TT-33 in compliance with Warsaw Pact ammunition standardization around the 9x18mm Makarov cartridge. A compact blowback design somewhat resembling the Walther PP, it is notable for a very heavy double-action trigger pull and strong recoil impulse relative to its small size.
