The FN 509 Compact MRD Compensated delivers full-size performance in a compact, optics-ready pistol designed for concealed carry. Its striker-fired operating system, 4.2-inch cold hammer-forged barrel, and factory auto-indexing compensator help reduce muzzle rise and support faster follow-up shots. The FN Low-Profile Optics Mounting System accepts a broad range of miniature red dot optics, while the all-black co-witness iron sights provide a dependable aiming solution. A shortened grip, enhanced texture, interchangeable backstraps, and fully ambidextrous slide stop and magazine release improve control and handling. This Flat Dark Earth configuration includes two 10-round magazines.
