Tall suppressor-height iron sights provide a clear sight picture over the threaded muzzle, and front and rear slide serrations offer confident manipulation.
The 5.3-inch cold hammer-forged stainless steel barrel is threaded 0.578x28, pairing durability with compatibility for common .45 ACP muzzle devices. The stainless-steel slide wears an FDE finish, matching the FDE polymer frame for a cohesive, duty-ready appearance.
Controls are fully ambidextrous, including the magazine release and the frame-mounted manual safety/decocker. The pistol uses a DA/SA hammer-fired system with an exposed ring hammer, giving the shooter both double-action first-shot capability and single-action precision.
A MIL-STD-1913 accessory rail supports weapon-mounted lights or other rail-mounted accessories. The frame includes interchangeable backstraps, and the pistol ships with three 15-round steel magazines for a total on-board capacity of 15+1.
The slide is marked "FN Columbia, SC USA," and the pistol is made in the USA. Overall fit and features align with the FNX Tactical series design intent for a configurable, feature-rich .45 ACP platform.
