American Made: FN America

The FN 509 Tactical is a 9mm striker-fired pistol based on the FN 509 series of handguns introduced by FN in 2017. It features FN’s patented Low-Profile Optics Mounting System, which enables the platform to accept more than 10 commercially available miniature red dot (MRD) optics that co-witness with the suppressor-height night sights, while remaining adaptable to future optics releases with no need for 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, pants pocket, or boot. An FN-signature 4.5-inch, cold hammer-forged, stainless-steel barrel with target crown, ½x28-inch threads that accept the bulk of 9mm suppressors available, and threaded 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.
