FNX<sup>™</sup>-45 Tactical

FNX-45 Tactical

Improving on the FNP-45 Tactical, developed for the U.S. Joint Combat Pistol Program, the FNX-45 Tactical 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. The checkered polymer frame is offered in Black and Flat Dark Earth and has a low-bore axis for reduced felt recoil and enhanced operator control. Two 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.
