The FN FNX-45 was brought to market after many years of research and development. It is modeled on the FNP-45 service pistol, which was introduced in 2007 as a part of the U.S. Military’s Joint Combat Pistol Program. The FNX-45 is the battle-tested and combat-proven history of FN firearms, now brought to market for the everyday shooter.

This polymer frame, hammer-fired pistol can be operated as either a double- or single-action. It features a stainless-steel barrel and slide, which has both front and rear slide serrations for ease of operation when conditions are sub-optimal or when using gloves. The enhanced ergonomics of the pistol include key features such as an ambidextrous slide lock, magazine release, and safety/decocking lever. Adjustable, interchangeable backstraps make it easy to find a grip size that fits you. The angle of the grip sits at 18 degrees off-square, providing a natural-feeling point of aim.

The FN FNX-45 ships with three 15-round magazines, delivering impressive capacity in .45 ACP. The handgun has a standard 3-dot sighting system, and the MIL-SPEC 1913 rail system provides the ability to attach accessories like your favorite laser or flashlight.

The FN FNX-45 packs the power of .45 ACP without compromising on capacity, making this handgun an ideal option for everyday service. The quality and engineering ensure that it will provide years of reliable and accurate operation at a price that you can feel great about.
