FN America recently announced the release of the new FN MRD pistol. The MRD is an optics-ready duty pistol designed specifically for agencies considering using miniature red dot optic-equipped sidearms, according to FN. Based on FN’s submission pistol for the U.S. Army Modular Handgun Trials, the 509 MRD includes improvements first seen in the earlier 509 series of pistols.

FN MRD Features

The FN 509 has quickly grown into one of the most popular handgun platforms. The 509 MRD utilizes FN’s Low-Profile Optics-Mounting System, which FN previously released on the FN 509 Tactical. Also, the system accepts more than 10 commercially available reflex sights, including the duty-grade Trijicon RMR, Leupold DeltaPoint Pro and Aimpoint ACRO P-1.

Better still, the optics-mounting system accepts the majority of miniature red dots on the market. Moreover, the system enables a low-profile mount, co-witnesses with iron sights. Additionally, the slide does not require any milling to accept the optic. Also, a slide cap, for use when not shooting with an optic, features raised sight wings to protect iron sight alignment during hard use. A textured ramp aids when racking the slide against a belt loop, pant pocket or boot, according to FN.

The MRD joins the FN law enforcement lineup, along with the Training and Simunition pistols released last year. For more information, visit us at
