The stainless steel, cold hammer-forged barrel measures 5.3 inches and is threaded .578x28 tpi. It features a polished chamber and feed ramp, pairing durability with smooth feeding. Twist rate is 1:16 RH.
The hammer-fired DA/SA system uses an external hammer with a manual safety and decocker. Controls are fully ambidextrous, including the safety/decocker, slide stop, and magazine release, supporting left- or right-handed use.
The optics-ready stainless slide is finished in Flat Dark Earth and includes front and rear serrations, an optic cover plate retained by two screws, an external extractor, and a loaded chamber indicator cut. Suppressor-height 3-dot sights provide a clear sight picture with an approximate 6.4-inch sight radius.
The Flat Dark Earth polymer frame integrates a MIL-STD-1913 accessory rail on the dustcover and comes with interchangeable backstraps for grip fit. Three factory 15-round magazines are included, each with witness holes to 15 rounds, delivering a 15+1 capacity in .45 ACP.
Markings include "MADE IN USA" and "FNH USA Fredericksburg, VA" on the slide. The model is marked FNX-45 Tactical with .45 ACP on the slide and barrel hood.
