FN 509 Compact MRD Pistol, 9mm, FDE, 12/15-Round

The FN 509 Compact MRD pistol in 9mm with a Flat Dark Earth finish (brand part no. FN 66-100574) trims the 509 platform further into a compact frame for concealed carry while retaining the mini red dot optics mounting system. FN America builds the pistol with a 3.7-inch cold hammer forged barrel and blackout iron sights, and interchangeable Flat Dark Earth backstraps tailor the grip to hand size. The trigger runs with no manual safety, and one 12-round and one 15-round magazine ship with the pistol alongside an FN soft case. Among optic-ready semi-auto handguns, this 509 Compact configuration favors concealed carriers who want red-dot compatibility.
