“The FN FNX pistol is a series of semi-automatic, polymer-framed pistols manufactured in Columbia, SC, by FN America (branded FNH USA), a division of Fabrique Nationale d’Herstal. 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, trinium night sights, and a loaded chamber indicator on the right side.” — Wikipedia
The FNX is closely related to the earlier FNP, which dates back to 2006. This means that the FNX has a relatively short lineage, and is not exactly a weapon with a long legacy. That may sound like a bad thing, but the truth is that the FNX being a newer clean-sheet design means that it is unhindered by design aspects of the past. It has been designed to be incredibly modular, easy-to-use, and readily adaptable. It is available chambered in 9×19mm Parabellum, .40 S&W, and .45 ACP.
The FNX family has a few neat design tricks, such as a unique slide design where the barrel and slide travel twice that of the average pistol to allow the recoil spring to absorb more momentum and transfer less of it to the user — taking some of the bite out of that .45’s backlash. The standard-issue magazines also include “witness holes” to help the user accurately gauge how many rounds remain.
The FNX45 as we know it in-game is specifically based on the top-tier FNX Tactical. Differences from the standard FNX include a threaded barrel (for adding a suppressor) and a mount on the right side for a reflex sight.
