Fn Fnx-45 .45 ACP 4.5 inch 15 Rounds Stainless Slide Polymer Frame

The FN FNX-45 is a robust .45 ACP semi-auto pistol from FN that blends service-pistol pedigree with user-friendly controls, offering a 4.5" stainless steel barrel and stainless slide for corrosion resistance and sustained accuracy, a hammer-driven double-action/single-action design for deliberate first shots and quick follow-ups, and a checkered polymer frame with interchangeable backstraps and lanyard eyelet to tailor the grip to hand size for duty, home defense, or range sessions. The FNX-45's fully ambidextrous manual safety/decocking levers, slide stop, and magazine release give left- and right-handed shooters confidence under stress, while the MIL-STD-1913 accessory rail accepts lights and lasers for low-light work or tactical training; it accepts 15-round magazines for extended carry capacity without frequent reloads. As a model derived from the FNP-45 developed under the U.S. Joint Combat Pistol Program, this FN series pistol brings service-grade ergonomics, reliable extraction, and straightforward maintenance to competitive shooting, patrol duty, and personal protection, and requires FFL transfer for legal purchase and delivery.
