FN 509T 9mm Luger 4.50 inch 10+1 Matte Finish Stainless Slide Optic Ready

The FN 509T Tactical brings the proven FN 509 series into a duty-ready, suppressor-capable platform with a 4.50" cold hammer-forged stainless steel threaded barrel (1/2" x 28) and a matte black, optic-ready/serrated stainless slide that uses FN's U.S. Patent No. 10/352654 Low-Profile Optics Mounting System to accept a wide range of miniature red dot optics while co-witnessing with suppressor-height 3-dot night sights; the 10+1 DAO 9mm Luger pistol mounted on a matte black polymer frame with interchangeable backstraps, Picatinny accessory rail and textured slide cap gives shooters a service-weight 27.9 oz package that handles like a duty pistol but remains comfortable on the range. Whether you're configuring a suppressed setup for reduced noise on long training sessions, fitting an MRD for faster target acquisition in competition, or equipping a patrol carry rig, the threaded barrel, durable slide, ambidextrous controls and textured racking surface make manipulation and mounting accessories straightforward. This FN model appeals to tactical shooters, law enforcement, and serious defensive-minded owners who require an optic-ready, suppressor-capable 9mm platform; transfer through an FFL is required.
