Description
With our patented Low-Profile Optics Mounting System and unparalleled modularity of the FN 509 platform, the FN 509 Compact MRD joins the ranks packing a full-size punch in a compact, optics-ready package. The pistol is 9mm and striker-fired with 3.7-inch barrel, standard 12+1 capacity and the capability to accept all higher capacity FN 509 magazines. The patented FN Low-Profile Optics Mounting System accepts nearly all commercially available miniature red dot optics and features blackout iron sights that co-witness. The improved controls aid in manipulation, the new improved texturing on the two included backstraps provides better recoil management, and a new flatter faced trigger allows for more controllable trigger press and cleaner break.Manufacturer FN America
