Brownells 75th Anniversary - A Shooting Heritage

New & Improved FN 509

The FN 509 Tactical is based on FN’s submission pistol that the U.S. Army tested for its Modular Handgun Trials but includes the significant improvements to the design that were implemented in the FN 509.

The pistol features FN’s patent-pending Low-Profile Optics Mounting System that enables the platform to accept more than ten commercially-available miniature red dot (MRD) optics that co-witness with the suppressor-height night sights and remain adaptable to future optics releases with no requirement of direct milling of the slide.

  • Barrel Length: 4.5”
  • Caliber: 9mm
  • Length: 7.4”
  • Sights: Night Sights

The slide cap, for use when not shooting with an optic, has raised sight wings that protect iron sight alignment if the pistol is dropped or jostled, and provides a textured ramp for racking the slide against a belt loop, pant pocket or boot. The FN 509 Tactical features a signature 4.5-inch, cold hammer-forged, stainless-steel barrel with target crown, ½” x 28 threads that accept the bulk of 9mm suppressors available and thread cap with integrated O-ring to prevent loosening during use complete the top end. Available in 10-round and 24-round capacities.
