Improving on the FNP™-45 Tactical, developed for the U.S. Joint Combat Pistol Program, the FNX™-45 Tactical 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.

Ships with two 15-round magazines with extended base plates, four interchangeable backstraps and a fitted, soft Cordura nylon case.

Vortex Viper Optic – 6 MOA Red Dot

A 6 MOA dot promotes rapid target acquisition, while providing a precise point of aim—getting shots down range and on target fast.

The Viper Red Dot’s super-low mounting height makes it the perfect solution for handguns with cutout slides. The Viper gives shooters the simplicity and speed advantage of a dot sight, while co-witnessing with suppressor height iron sights. The trade off? Nothing. The 6 MOA dot diameter gets shooters on target fast.

Battery Life: Up to 150 hours on highest setting. Up to 30,000 hours on lower settings.
