With our patented Low-Profile Optics Mounting System and proprietary auto-indexing compensator, the FN 509 MRD compact with quick-detach compensator joins the ranks packing full-size performance in a compact package. The pistol is striker-fired with a compensated barrel featuring an approximate 25 percent muzzle flip reduction. The optics mounting system accepts nearly all major optic footprints and features all-black co-witness iron sights. The ambidextrous controls aid in manipulation and the texturing on the two included backstraps provides better recoil management.
