FN 509 Midsize MRD 9mm Luger 4″ Barrel Handgun

Take your everyday carry to the next level with the FN 509 Midsize MRD. This refined version of the FN 509 Midsize incorporates the FN Low Profile Optics Mounting System, enabling direct attachment of more than 10 different miniature red dot optics to your concealed carry pistol. Built around a 4″ barrel and slide with integrated optics mounting capability, the FN 509 Midsize MRD pairs a midsized frame with 10-round capacity magazines and accepts larger capacity FN 509 magazines when used with a sleeve. Enhanced controls streamline operation, while the new texturing on the two included backstraps improves recoil management. A newly designed flatter faced trigger delivers a more controllable and consistent break.
