FB P-64
Produced by FB Radom
The P-64 is a Polish semi-automatic pistol designed to fire the 9×18mm Makarov cartridge. The pistol was developed in the late 1950s at the Institute for Artillery Research (Polish: Zakład Broni Strzeleckiej Centralnego Badawczego Poligonu Artyleryjskiego, which later became the Military Institute of Armament Technology, Polish: Wojskowy Instytut Techniczny Uzbrojenia w Zielonce—WITU) by a team consisting of: W. Czepukajtis, R. Zimny, H. Adamczyk, M. Adamczyk, S. Kaczmarski and J. Pyzel. The P-64 is also known as the CZAK (an acronym of the designers' last names with the exception of J. Pyzel, who joined the team after the name had been established).
