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 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 threaded stainless steel barrel with target crown and thread cap. Includes two magazines two interchangeable backstraps and FN logo soft pistol case.
