Description

<p>The FNX series features an ergonomic polymer frame with a low-bore axis for less felt recoil and improved control. The grip panels are checkered and ribbed for comfortable, non-snag carry. Two interchangeable backstraps quickly adapt the FNX to your hand size. The profiled stainless steel slide has cocking serrations front and rear, and the 4.5&quot; cold hammer-forged stainless steel barrel delivers pinpoint accuracy. Ambidextrous operating controls (decocking/safety lever, slide stop, and magazine release) make the FNX perfect for competition or personal defense. It ships with two (2) magazines and a lockable hard case. Made in the USA. This 45 ACP model has an FDE frame with a black slide and a 15+1 capacity.</p>
