FN 509 Full Size MRD NMS 9mm Blue/Black Pistol

The FN 509 Full Size MRD NMS is a 9mm semi-automatic pistol in Blue/Black, built on FN's 509 platform. It has a 4.5-inch barrel, a 7.4-inch overall length and weighs 26.9 ounces. It holds 10+1 rounds, and two 10-round magazines are included. The Low Profile Optics Mounting System includes adapter plates for compatible red dot optics, and all-black co-witness iron sights provide a backup aiming system.

The full-size frame and longer sight radius give this model a steady, controllable feel on the range. The internal trigger safety means the pistol has no manual safety, so the operation is simple. The polymer grip frame keeps the weight manageable through a long session. Buyers should check their state's rules on capacity and permits, which apply at pickup.
