FN 509 Tactical 9mm Black 4.5″ Threaded Barrel

The FN 509 Tactical is a robust addition to the FN 509 family, evolving from the design submitted for the U.S. Army's Modular Handgun Trials. This 9mm striker-fired pistol features FN's patent-pending Low-Profile Optics Mounting System, compatible with a wide range of miniature red dot optics. The system allows co-witnessing with suppressor-height night sights, ensuring adaptability to future optics without slide modifications. The 4.5-inch cold hammer-forged stainless steel barrel is threaded (1/2 x 28) for suppressor use and includes an O-ring retention thread cap to prevent loosening.
