This FNX-45 Tactical is a semi-automatic, short-recoil pistol built around a stainless steel slide and a 5.3 inch cold hammer-forged barrel. The barrel is extended and threaded (.578x28) with a thread protector, and uses a 1:16 RH twist. Threaded is a core feature on this model, supporting its tall sight setup.
The slide is finished in Flat Dark Earth and includes rear cocking serrations, an external extractor, and an optic cut with a cover plate. Suppressor-height 3-dot night sights (tall front and serrated rear) and a 6.4 inch sight radius provide a clear, elevated sight picture.
Controls are fully ambidextrous with a manual safety/decocker and slide stop, plus an ambidextrous, reversible magazine release. A visual witness hole in the barrel hood (visible through the ejection port) serves as the loaded chamber indicator. A MIL-STD-1913 accessory rail is integrated into the polymer FDE frame, which also includes interchangeable backstraps and a lanyard loop.
Chambered in .45 ACP, the FNX-45 Tactical offers 15+1 capacity and comes with three 15-round factory magazines. An aftermarket rubber over-grip sleeve is installed. Made in the USA.
