The FNS offers the simplicity of double-action, striker-fired operation in a lightweight, polymer-framed design that's easy to carry. All operating controls are fully ambidextrous for ease of use with either hand and from any shooting position. Both the slide and barrel are stainless steel with front serrations, while the checkered polymer frame has two interchangeable backstraps and lanyard eyelets. The MIL-STD 1913 under-frame rail accepts tactical lights and lasers.
The FNS-9 Compact provides the same features as the standard models with a 3.6" barrel and a snag-free design for better concealment and a faster draw. The front sight also has a larger dot for faster target acquisition. Every FNS-9 Compact ships with three magazines.
