FN 509 Midsize MRD 9mm Pistol – FDE, No Manual Safety, 4″ Barrel, 15-Round, Optic-Ready

Upgrade your everyday carry with the FN 509 Midsize MRD in Flat Dark Earth (FDE) — a purpose-built, optic-ready 9mm pistol engineered for concealed carry without compromise. Featuring FN’s Low Profile Optics Mounting System, this pistol supports direct mounting of more than 10 different miniature red dot sights right out of the box, with no adapter plates required. The 4-inch barrel and slide strike the ideal balance between concealability and accuracy, while the mid-sized frame delivers a comfortable, secure grip for a wide range of hand sizes. Chambered in 9mm Luger, the FN 509 Midsize MRD ships with two 15-round magazines and is also compatible with higher-capacity FN 509 magazines when used with the included sleeve. The No Manual Safety (NMS) configuration streamlines the draw-to-fire process for those who prefer a clean, consistent trigger pull. Refined controls and an updated flat-faced trigger offer a more controlled press and a cleaner break shot after shot, while improved backstrap texturing on both included backstraps enhances grip and recoil management. Whether you’re building a duty-ready carry setup or adding a quality optic-ready pistol to your collection, the FN 509 Midsize MRD FDE delivers proven FN reliability at a competitive price.
