The FN FNX pistol is a series of semi-automatic, polymer-framed pistols manufactured in Columbia, South Carolina, by FN America (branded FNH USA), a division of Fabrique Nationale d'Herstal.

[5] All variations also include a Picatinny rail, tritium night sights, and a loaded chamber indicator on the right side.

The barrel and recoil spring then separate from the slide to complete the disassembly procedure.

It features a threaded barrel, Suppressor height tritium night sights "rear yellow front green" and a milled slide to install optics like a micro red dot sight.

The FNX barrel and slide travel up to twice the distance of some other semiautomatic pistols 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.
