FN Herstal 509 Tactical 9mm

FN 66100844 509 Tactical 9mm Luger Caliber with 4.50" Threaded Barrel, 17+1 or 24+1 Capacity, Matte Black Finish, Picatinny Rail Frame, Serrated/Optic Cut Slide, Interchangeable Backstraps Grip, No Manual Safety & Night Sights Includes Viper Red Dot

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 a patent-pending Low-Profile Optics Mounting System that enables the platform to accept miniature red dot (MRD) optics that co-witness with the suppressor-height night sights. The slide cap 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, 1/2" 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. The 509 Tactical ships with two interchangeable backstraps and FN logo soft pistol case.
