FN 509 Midsize MRD 9mm 4" 15rd FDE Holosun 407C Pistol

This FN 509 Midsize MRD comes ready to shoot with a Holosun 407C red dot in the box. The midsize 9mm pairs a 4" cold hammer forged stainless steel barrel and recessed target crown with a flat dark earth frame and slide. The slide is cut for FN's Low Profile Optics Mounting System, and co-witness height iron sights stay usable through the window of the dot. Standard capacity is 15 rounds, and the frame accepts larger 509 magazines with a sleeve.

FN gave the midsize frame improved controls, more aggressive texture on the two included backstraps, and a flatter faced trigger for a more controllable press and cleaner break. The slide stop and magazine release are fully ambidextrous, and an external extractor doubles as a loaded chamber indicator. A MIL-STD-1913 rail takes a weapon light. At 26.5 oz with a 4" slide, it carries more comfortably than a full size duty pistol while keeping a full grip for fast follow up shots. Two magazines, a case, a locking device and the owner's manual come with the pistol and optic.
