SHOT Show 2019: FN Releases Optics-Ready FN 509 Duty Pistol

FN America released the FN 509 MRD pistol, an optics-ready duty pistol at SHOT Show 2019. The company says the new FN 509 MRD was designed specifically for agencies considering miniature red dot optic-equipped pistols for their officers.

The FN 509 MRD pistol features the company’s patent-pending FN Low-Profile Optics-Mounting System, first introduced on the FN 509 Tactical. The optics-mounting system can accept more than 10 commercially available miniature red dot optics, including the duty-grade Trijicon RMR, Leupold DeltaPoint Pro, and the recently released Aimpoint ACRO P-1.

The optics mount accepts the majority of MRDs on the market with no need to direct mill the slide, allowing for a low-profile mount and co-witness with 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.

The FN 509 MRD joins the FN 509 law enforcement-specific line-up alongside the new Training and Simunition pistols released last year. Agencies interested in the FN 509 MRD should contact le@fnamerica.com for a price quote.
