The FN FNP pistol is a series of semi-automatic, polymer-framed pistols manufactured in Columbia, South Carolina, by FNH USA, a division of Fabrique Nationale de Herstal. The pistol debuted in early 2006 and is chambered for the .45 ACP.
The FNP 45 is short recoil operated, locked breech pistol. The barrel is operated using a Browning cam system, and it locks to slide with single lug engaging large ejection port. Frame is made from high impact-resistant polymer. Double Action trigger system with exposed hammer has internal firing pin safety, with decocking or safety levers located at the both sides of the frame. Firing pin safety is standard, and the magazine safety is optional. The trigger / hammer module is formed as a single unit, easily detachable from the frame for inspection, maintenance or replacement. Optional hammer units can be found in DAO variety or in standard DA version but with manual safety / decock levers instead of the basic decock-only levers. Other easily replaceable units include the barrel cradle / slide rail module and the grip backstraps. Grip backstraps are available in two variations, with straight or curved shape. Standard sights are provided with white inserts and are dovetailed into the slide.
