FN 509 Tactical 9mm Luger Full-Size Pistol with Flat-Face Trigger, Threaded Barrel & Compensator
This FN 509 Tactical combines the proven FN 509 platform with factory-ready suppressor features and thoughtful custom upgrades. A cold-hammer-forged, stainless steel threaded barrel pairs with a black Herrington Arms compensator to control recoil and accept muzzle devices. The red-anodized flat-face trigger shoe shortens perceived pull length, while FN’s Low-Profile Optics Mounting System lets you add today’s most popular red-dot footprints without extra machining. Four 17-round magazines and one 24-round extended magazine round out a high-capacity, duty-ready package.

Originally developed for the U.S. Army’s Modular Handgun System trials, the 509 Tactical carries battle-proven DNA. Its fully ambidextrous controls—slide stop and magazine release—let right- or left-handed shooters run the gun without compromise.
The slide’s forward and rear serrations give a solid purchase even with gloves, while raised rear wings protect the optics cut and aid racking. Suppressor-height tritium night sights co-witness through most micro red dots for immediate backup.
FN’s cold-hammer-forged, stainless steel barrel is threaded 1/2-28 TPI and fitted with the included compensator, delivering both durability and flat shooting. The polymer frame features an accessory rail and interchangeable backstraps to tailor grip size.
A nickel-Teflon-coated fire-control group and the upgraded flat-face trigger provide a crisp break and quick reset. Combined with the generous 24-round magazine, this setup offers extended firepower in a package ready for duty, competition, or home defense.
