The FN 509 Tactical FDE is an optic and suppressor ready, full sized, 9mm striker fired pistol, with an incredible 17/24+1 capacity. This pistol is based on FN’s submission pistol for the U.S. Army’s Modular Handgun Trials and includes improvements to the design that were incorporated in the civilian version.

The 509 Tactical uses a unique, patented Low-Profile Optics Mounting System that enables the gun to accept more than ten commercially-available miniature red dot (MRD) optics that will co-witness with the suppressor-height night sights.

When not shooting with an optic, the slide cap has raised wings that protect the suppressor height Trijicon 3-Dot green tritium night sights and provide a ramp for racking the slide against a belt loop, pant pocket or boot. The heart of the 509 tactical is it’s 4.5″ cold hammer-forged, stainless-steel threaded barrel with a target crown and polished chamber and feed ramp. The ½” x 28 threads will accept most 9mm suppressors and are protected by a thread cap with integrated O-ring to prevent loosening. Standard 509 features include a fully ambidextrous slide stop lever and magazine release along with an accessory rail for mounting your choice of weapon light.
