FN 509 Tactical FDE

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. This pistol features the FN’s patent-pending Low-Profile Optics Mounting System that enables this platform to accept over nine commercially-available miniature red dot (MRD) optics that co-witness with the suppressor-height night sights (such as RMR, Vortex, Burris, etc..) 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 handled roughly, and provides a textured ramp for racking the slide against a belt loop, pant pocket or boot. That’s right! You can safely “Boot Rack” this here firearm! An FN-signature 4.5-inch, cold hammer-forged, stainless-steel barrel with target crown, 1/2×28  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.
