Features and construction

FN built this pistol on the proven FNS Compact architecture. The cold hammer-forged stainless-steel barrel includes a recessed target crown and a polished chamber and feed ramp for reliable feeding and longevity. The Flat Dark Earth slide paired with an FDE polymer frame gives a low-reflective, service-ready finish while the polymer grip uses enhanced texture for faster follow-up shots in wet or adverse conditions.

Controls and ergonomics

The pistol is striker-fired with no manual safety and includes an external extractor and a loaded chamber indicator. Controls are fully ambidextrous: slide stop lever and magazine release work for strong- or weak-hand manipulation. Interchangeable backstraps (two FDE backstraps included) let users tune the shorter Midsize grip for concealment or duty carry without adding bulk.

Accessories and tactical readiness

A MIL-STD-1913 accessory rail accepts lights or lasers, and suppressor-height night sights are installed out of the box — optic cut is not part of this listing, and optics are not included. The package includes one 15-round and one 24-round magazine plus a FN logo soft pistol case, making it ready for range or service straight from the box.
