The FN FNS pistol is a series of semi-automatic, polymer-framed pistols manufactured in Columbia, SC, by FNH USA, a division of Fabrique Nationale d'Herstal.[4] The pistol is chambered for the 9x19mm Parabellum and .40 S&W cartridges.

Design details[edit]

The FNS pistol was based upon the FN FNX platform.[1] The FNS platform has similar ergonomics to the FNX but introduces a double-action, striker-fired functionality.[citation needed]

Operating mechanism[edit]

Like other FN pistols, the FNS is a short recoil operated pistol. It is a pre-set striker fired semi-automatic pistol, meaning the trigger system is of the hammerless short double action only type. The trigger pull is between 25 N (5.6 lbf) to 35 N (7.9 lbf).[citation needed]

All variations also include a hammer forged stainless steel barrel, Picatinny rail, fixed three-dot combat sights, and a loaded chamber indicator on the right side.[5]

Standard Features[edit]

The FNS series of the pistols all include ambidextrous magazine releases, and slide stop release levers.[5]


The FNS has 4 standard safety features:

  1. A trigger safety, similar to that seen on a Glock, which prevents the weapon from discharging without pressure on the trigger.[5]
  2. A firing pin safety which prevents the striker from hitting the primer without the trigger being pulled.[5]
  3. A drop safety which prevents the sear from rotating to release the striker unless the trigger is pulled.[5]
  4. An out-of-battery safety which prevents the sear from releasing the striker if the slide is not fully forward.[5]

As a fifth safety feature the FNS pistols can also have an optional manual safety.


As of December 2012, the only variants available of the FNS-9 and FNS-40 pistol have solely cosmetic differences. Both pistols are available in standard black featuring a dark colorednitrided slide and matte black frame or with a two-tone finish featuring a silver colored stainless steel slide and matte black frame.[3]
