The FNX™ offers all of the features that dedicated handgunners 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. Two interchangeable backstraps quickly adapt the FNX™ to fit your hand size. The profiled stainless steel slide has cocking serrations front and rear, and the 4-inch cold hammer-forged stainless steel barrel delivers pinpoint accuracy. Ambidextrous operating controls make the FNX™ perfect for competition or personal defense.
