With FN’s patented Low-Profile Optics Mounting System and proprietary auto-indexing compensator, the FN 509 compact MRD compensated joins the ranks packing a full-size punch in a compact package. The pistol is striker-fired with a compensated barrel featuring an approximate 25 percent muzzle flip reduction. The FN 509 compact MRD compensated comes standard with two 10 round magazines for individuals in states with high capacity limitations. 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 ambidextrous controls aid in manipulation and the texturing on the two included backstraps provides better recoil management.
