The FN 509 is a striker-fired double-action only semi-automatic pistol designed and manufactured by FN America, the American subsidiary of FN Herstal.

History
The 509 was revealed to the public on April 17, 2017. It was not the pistol that FN entered into the Modular Handgun System competition, but was developed from it.

On April 25, 2017, FN America announced that Brink's had selected the 509 for issue to its security guards.

Design and features
The 509 was developed from FN's submission to the United States Armed Forces' XM17 Modular Handgun System competition, itself developed from the FNS Compact. The pistol is fed by a detachable box magazine, with a 17-round capacity as standard; magazines limited to 10 rounds are available in jurisdictions with high-capacity magazine bans.

The 509 has front and rear cocking serrations. It also features fixed 3-dot luminescent iron sights as standard, with 3-dot night sights available to law enforcement agencies and militaries.

The 509 features a cold hammer-forged stainless steel barrel, with a recessed target crown and a polished chamber and feed ramp.

The frame features interchangeable backstraps, which allows users to change the size of the pistol grip to better suit their hand. It also features a Picatinny rail on the underside of the frame, for mounting accessories such as weapon-mounted lights and laser sights.

The magazine release button and slide release lever are both fully ambidextrous. The 509 lacks any manual safeties.
