FN 509 (66-100375) Tactical Black w/ 17rd and two 24rd Magazines is an evolution of FN's iconic submission pistol that's seen enormous use throughout the military in recent years. The FN 509 family brings a series of patent-pending features to users, offering unrivaled stability and accuracy for a hand-gun.

The FN 509 offers some significant improvements of the US-army-tested predecessors used in the Modular Handgun Trials.

The pistol comes with the company's Low-Profile Optics Mounting System. This feature makes it more compatible with many of the standard optics tools currently available on the market. And it comes with a slide cap which is helpful when shooting without optics. You get helpful sight wings if you happen to drop the pistol or it gets jostled. And there's a textured ramp that makes it easy for racking the slide against a boot, pant pocket, or belt loop.

Features of the FN 509 Tactical Black w/ 17rd and two 24rd Magazines

• Cold hammer-forged stainless-steel barrel
• 5.5 to 7.5 lbs
• Features the FN Low-Profile Optics Mounting System

The FN 509® Tactical, an extension of the FN 509 family, 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 the company’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. 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. An FN-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. Lastly, the 24-round magazines, nearly identical in length to the pistol’s slide, maximize ammunition capacity without impacting carry convenience.
