Design details

The FNS pistol is based on the FN FNX.[1] The FNS has similar ergonomics to the FNX but introduces a double-action, striker-fired functionality.[9][10]

Operating mechanism

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) and 35 N (7.9 lbf).[2]

All variations also include a hammer-forged stainless steel barrel, Picatinny rail, fixed three-dot combat sights (standard or night sights), and a loaded chamber indicator on the right side.[11]

Standard features

The FNS series of the pistols all include ambidextrous magazine releases, and slide stop release levers.[11]

Safety

The FNS has four 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.[11]
  2. A firing pin safety which prevents the striker from hitting the primer without the trigger being pulled.[11]
  3. A drop safety which prevents the sear from rotating to release the striker unless the trigger is pulled.[11]
  4. An out-of-battery safety which prevents the sear from releasing the striker if the slide is not fully forward.[11]

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

Variants

A "long slide" version, known as the FNS-9LS and FNS-40LS, was introduced in 2012 designed in partnership with the Baltimore County Police Department specifically for the department.

A compact version, known as the FNS-9C and FNS-40C, was introduced in 2015. The compact version comes with two short magazines. One has a "pinkie rest" baseplate while the other has a flat baseplate. Magazine capacity for the 9mm version is 12 rounds and for the .40 S&W version is 10 rounds. The compact versions can also use full size magazines with the addition of a removable grip sleeve.

A full size 9mm pre-loaded striker pistol, known as the FN 509, was introduced in early 2016 with it being part of the XM17 Modular Handgun System competition. It was released for public sale in 2017. It is fully ambidextrous and comes in two versions, one version having manual safety and another without it. It also comes with a Picatinny rail for various attachments.[12]

All versions are available in two finishes: a standard black finish featuring a dark colored/nitrided slide and matte black frame or a two-tone finish featuring a silver colored stainless steel slide and matte black frame.[2][5] At least one variant, the FNS-9C (compact) is available in solid dark earth coloration.
