FN 509 Midsize MRD 9mm Luger 4" 15-Round Pistol

The FN 509 Midsize MRD is a polymer-framed, double-action pistol chambered in 9mm Luger, designed for concealed carry. It uses the FN Low Profile Optics Mounting System, which allows direct mounting of more than 10 different miniature red dot optics on the slide, with co-witness iron sights for use without an optic.

The pistol has a 4-inch barrel and slide, a midsized frame, and a standard 15-round capacity. It weighs 1.66 pounds and measures 7.4 inches overall. The included two interchangeable backstraps are textured to help with recoil management, and the trigger has a flatter face for a more controllable press. The finish is matte black.

The package includes two magazines. Larger-capacity FN 509 magazines can be used with a sleeve.
