FN 509 Compact MRD with Compensator – FDE 9mm Pistol, 4.02″ Barrel, Optics Ready

The FN 509 Compact MRD with Compensator in Flat Dark Earth delivers full-size performance in a carry-friendly package. Featuring FN’s patented Low-Profile Optics Mounting System, this striker-fired 9mm pistol accepts nearly all major optic footprints right out of the box, backed by all-black co-witness iron sights for a seamless transition to your preferred red dot. The proprietary auto-indexing quick-detach compensator delivers an approximate 25% reduction in muzzle flip, keeping your sights on target shot after shot. The ambidextrous controls make this pistol equally suited for left- and right-handed shooters, while two interchangeable backstraps with aggressive texturing ensure a confident, customizable grip and improved recoil management. Chambered in 9mm Luger with a 4.02″ barrel and a crisp 5.5–7.7 lb. trigger pull, the FN 509 Compact MRD is built for concealed carry, home defense, and range performance alike.
