This FNX-45 Tactical is a U.S.-made, full-size .45 ACP built in Columbia, South Carolina. It uses a DA/SA system with an ambidextrous, frame-mounted safety/decocker, allowing cocked-and-locked carry for those who prefer that mode. Fully ambidextrous controls support both left- and right-handed operation.
The 5.3-inch cold hammer-forged stainless steel barrel is threaded .578x28 TPI, paired with suppressor-height raised 3-dot night sights for a clear sight picture. The slide is stainless steel with a black finish, featuring front and rear serrations, an external extractor, and an optics cut with a cover plate.
The black polymer frame integrates a MIL-STD-1913 three-slot accessory rail, interchangeable backstraps for fit tuning, and a lanyard loop. Sight radius measures 6.4 inches, and the pistol carries a 15+1 capacity with .45 ACP using steel double-stack magazines.
Overall dimensions are 8.6 inches in length, 6.5 inches in height, and 1.58 inches in width, with an unloaded weight of 33.3 ounces. Introduced commercially in 2012 as the successor to the FNP-45 Tactical, this model delivers proven .45 ACP performance with modern features and U.S. manufacturing.
