The FN FNX pistol is a series of semi-automatic, polymer-framed pistols manufactured in Columbia, SC, by FNH USA, a division of Fabrique Nationale d'Herstal. The pistol is chambered for the 9×19mm Parabellum , .40 S&W, and .45 ACP cartridges.
All variations of the pistols (save some law enforcement models that are decock only) include ambidextrous safety/decocking levers, magazine releases, and slide stop release levers. All variations also include a Picatinny rail, fixed three-dot combat sights, and a loaded chamber indicator on the right side. New models are sold in a plastic hard case with three magazines, and two interchangeable backstraps. As of 2012, new models include 4 interchangeable backstraps rather than two. One is shipped on the weapon and three extra in the case. The backstraps are two different thicknesses and two different patterns (a cross-hatch pattern similar to the sides of the grip, and horizontal lines similar to the front of the grip).
Field stripping is accomplished by locking the slide to the rear, rotating the takedown lever clockwise ninety degrees and releasing the slide stop while carefully allowing the slide to be pushed forward out of the frame. The barrel and recoil spring then separate from the slide to complete the disassembly procedure.
As of the beginning of October 2012, the only variants of the FNX 9 and FNX 40 pistol were purely cosmetic: both the FNX-9 and FNX-40 are available with the slide finished in matte black or stainless steel. The FNX 45 was released at the beginning of October 2012. It is currently available in Black, Stainless, and FDE (flat dark earth). The FNX 45 has magazines that come with 12 witness holes, numbering from 4 to 15, enabling the shooter to more accurately gauge the number of rounds left. This is in contrast to the original FNX having a hole marked 5, 10, and 14, for the FNX 40, or 5, 10, 15, 17 for the FNX 9.
The FNX Tactical was released in .45 ACP shortly after the initial production runs of the FNX 45. It features a threaded barrel and a mount to install a reflex sight on the slide.
The FNX is a short recoil operated pistol, much like many other centerfire pistols on the market. Its difference lies in the distance the barrel and the slide travel prior to the barrel dropping and unlocking. The FNX barrel and slide travel up to twice the distance of some other semiautomatic pistols, such as the Springfield XDm (HS2000), before separating. This helps to reduce the felt recoil of the pistol by allowing the spring to absorb more momentum from both the barrel and the slide.
The pistol is hammer fired, as opposed to striker fired; this allows the pistol to be fired in either Single Action or Double Action mode. Its safety mechanism is based on the safety found on a M1911. It is possible to cock the hammer to the rear and engage the safety simultaneously to carry the weapon "cocked and locked". The safety lever acts as a decocker when pushed downward.
Unlike other handguns from companies such as Glock, Sig Sauer, HK, and others, the FNX does not have a large aftermarket for parts and upgrades. The few companies that make custom parts for these guns do so infrequently. Some of the modifications include barrel changes, trigger jobs, holsters, and Metal Safety/decocker levers.
Several holster makers have begun offering holsters for the pistol, and include Garrity Gunleather, CrossBreed, Safariland, and Fobus.
