FN Herstal Pistols for FNX models in .45 ACP

FN Herstal 66-100351 FNX-45 Tactical 45 ACP, 5.3in Barrel, 15 Rounds, Flat Dark Earth/Black

Improving on the FNP-45 Tactical, developed for the U.S. Joint Combat Pistol Program, the FNX-45 Tactical FDE was born and bred for battle. Like its legendary FN forefathers, this combat handgun was designed to not only survive the battlefield, but to emerge victorious. It is the latest in technological advancements in handgun engineering, offering .45 ACP performance and a host of unique features that no other handgun can match.

Its 15-round magazine is precisely engineered to take a dive to the prone position and naturally roll up toward the target. The checkered polymer frame has a low-bore axis for reduced felt recoil, enhanced operator control, and a grip angle that provides unmatched natural point of aim. Four interchangeable backstraps come standard to quickly customize the grip feel. All operating controls are fully ambidextrous for ease of use. The 5.3? cold hammer-forged stainless steel barrel has a threaded muzzle to accept sound suppressors, compensators, and other accessories. The stainless steel slide has high-profile combat night sights and includes two mounting bases to accept multiple styles of optional red-dot electronic sights. Also offered as a non-threaded barrel model, ships with a 10rnd magazine. (State Compliant Model)
