The FN 509® Tactical
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. Like the optics mounting system, FN’s team of engineers set out to develop the ultimate tactical pistol by addressing the market’s existing limitations.
As a result, the FN 509 Tactical features 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. Lastly, the 24-round magazines, nearly identical in length to the pistol’s slide, maximize ammunition capacity without impacting carry convenience.
The optics mount accepts the majority of MRD’s on the market with no need to direct mill the slide, allowing for a low-profile mount and co-witness with the suppressor-height iron sights. 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.
