This particular model comes with night sights and 3 17rd magazines.
The FNS™-9 offers the simplicity of double-action striker-fired operation with the option of a manual safety. The slide stop lever and magazine release are all fully ambidextrous for ease of operation with either hand from any firing position. Both the slide and barrel are stainless steel, and the checkered polymer frame has two interchangeable backstraps with lanyard eyelets. A MIL-STD-1913 mounting rail on the underside accepts tactical lights and lasers.
