The P-11 is a semi-automatic, locked-breech, double-action only (DAO), pistol, chambered for the 9mm Luger cartridge. Ten round and optional twelve round magazines are available. The P-11 is compact and lightweight, thanks to its locked breech. Its ergonometry, perceived recoil and practical accuracy are comparable to much larger guns. The P-11 is especially well suited for plain-clothes police officers, security personnel, or as a secondary weapon for military service members.
