The FNX™-45 is the result of years of innovative product development and advanced engineering techniques. Modeled after the FNP™-45 service pistol introduced in 2007 under the U.S. Joint Combat Pistol Program, the FNX™-45 is a double-action/single-action hammer-driven pistol with highly enhanced ergonomics. Its manual safety/decocking levers, slide stop lever, and magazine release are all fully ambidextrous for ease of operation with either hand and from any firing position. Both the slide and barrel are stainless steel. The FNX™-45’s checkered polymer frame has multiple interchangeable backstraps with lanyard eyelets. A MIL-STD-1913 mounting rail on the underside accepts tactical lights and lasers.

LE & Military pricing on request.
