The FN 509 is a polymer frame striker-fired semi-automatic pistol manufactured by FN America, a division of FN Herstal.

History

As part of the XM17 Modular Handgun System competition (MHS) initiated in September 2015, FN Herstal entered a polymer-framed, striker-fired pistol, derived from the FN FNS. [2]

After SIG Sauer won the competition in January 2017 with a modified version of the P320, [3] [4] FN America brought a version of their entry, now known as the FN 509, to the commercial market. [5]

FN sought consultation from retired Delta Force operator Larry Vickers during early development of the FN 509. [6]

FN America stated that during development and testing of the MHS entry and the FN 509, over a million rounds of ammunition were used. [7]

Design

The FN 509 is a striker-fired handgun with a stainless steel slide with ferritic nitrocarburizing finish and a polymer frame.

Black and flat dark earth (FDE) colorings are available.

The FN 509's barrel length is 4.0 inches (100 mm) while employing a full-sized grip. The slide has serrations on both front and back, for easy slide manipulation

The FN 509 features a Picatinny rail located forward of the trigger guard. The backstrap of the grip accepts interchangeable inserts; one arched and one flat. [5]

Operation

The FN 509 features double-action operation with magazine releases and slide locks present on both side of the gun. [8]

Instead of a manual safety, the 509 includes an integrated trigger safety (the articulated trigger type like the FN FNS) as part of its four passive safety systems: a striker block, a drop safety, a trigger disconnect and a trigger safety lever. [8]

Magazines

The FN 509 primarily uses 17-round magazines; 10-round magazines are available for states with a high-capacity magazine ban.

Ammunition

While the FN 509 is primarily chambered in 9×19mm Parabellum, FN Herstal also offers the model in other calibres.
