Product Description
The FNX offers all of the features that dedicated hand shooters want. The ergonomic polymer frame has a low bore axis for less felt recoil and improved control. The grip panels are checkered and ribbed for comfortable, no-snag carry. Four interchangeable backstrap inserts quickly adapt the FNX to your hand size. The profiled stainless steel slide has cocking serrations front and rear and the 4" hammer-forged, stainless steel barrel delivers pinpoint accuracy. Ambidextrous operating controls make the FNX perfect for competition or personal defense. Every FNX is made in the USA.
