The 4.5-inch stainless barrel is cold hammer-forged for longevity and features a polished feed ramp that supports reliable feeding with varied bullet profiles.
Fully ambidextrous controls—safety/decocker, slide stop, and magazine release—allow seamless operation from either hand. The reversible mag release further personalizes control placement.
The stainless slide wears a durable satin finish and incorporates front and rear cocking serrations, an external extractor with a loaded-chamber witness hole, and fixed three-dot combat sights for fast sight acquisition.
A glass-fiber-reinforced polymer frame keeps weight manageable while providing an integrated MIL-STD-1913 rail for lights or lasers, interchangeable backstraps for grip tailoring, and molded texturing for a secure hold.
The FNX-45’s double-action/single-action trigger, external spur hammer, and 15+1 capacity offer a versatile balance of safety, first-shot confidence, and sustained firepower in a full-size .45 ACP package.
