FN FNX-45 Tactical Pistol 45 ACP 5.3″ Barrel Night Sights Polymer

The FN FNX 45 Tactical delivers high-capacity .45 ACP firepower, double-action/single-action (DA/SA) hammer-fired control, and duty-ready versatility. Evolved from the U.S. Joint Combat Pistol program, this tactical handgun combines a cold hammer-forged 5.3-inch threaded barrel with an ergonomically textured polymer frame designed for duty, tactical shooting, and home defense.

Outfitted with factory suppressor-height tritium night sights, the slide is factory-cut to accept red dot optics via FN’s Low-Profile Optics Mounting System™. Holding a 15+1 round capacity, the frame features fully ambidextrous operating controls—including the decocker/manual safety lever, slide stop, and magazine release—ensuring intuitive handling for left- and right-handed shooters alike.
