The FN FNX-45 Tactical (brand part no. 66101633) is a .45 ACP double-action/single-action pistol built for shooters who want a duty-grade handgun ready for a suppressor and a red-dot straight out of the case. FN America machines the slide and cold-hammer-forged barrel from stainless steel, threading the muzzle at .578×28 for sound suppressors and other muzzle devices, while fixed three-dot night sights and two included optics mounting plates support a red-dot sight. The polymer frame ships with two interchangeable backstraps and fully ambidextrous controls for right- or left-handed shooters. Among semi-auto handguns, the FNX-45 Tactical favors shooters who want a full-size .45 ACP duty pistol ready for suppressors and optics.
