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 the company’s patent-pending Low-Profile Optics Mounting System that enables the platform to accept more than ten commercially-available miniature red dot (MRD) optics that co-witness with the suppressor-height night sights and remain adaptable to future optics releases with no requirement of direct milling of the slide. The slide cap, for use when not shooting with an optic, 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, ½” 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. Lastly, the 24-round magazines, nearly identical in length to the pistol’s slide, maximize ammunition capacity without impacting carry convenience.
About the Red Dot
Make your AR, pistol, or shotgun even more poisonous with the Venom Red Dot sight. A 6 MOA dot promotes rapid target acquisition, while providing a precise point of aim—getting shots down range and on target fast.
The durable, machined aluminum housing ensures the unit will stand up to whatever you throw at it. High-quality, fully multi-coated lens offers a clean, wide field of view. Our top-load system makes changing the CR 1632 battery a snap and alleviates the need to remove the sight when switching the power source. The power and dot intensity controls are conveniently located on the left side of the unit. Flush 1 MOA windage and elevation adjustments are super sleek and make sighting in a breeze.
