The FN 509 grew directly out of FN's entry in the U.S. Army's handgun trials, and it carries that DNA in its trigger, its ergonomics, and its durability testing. The Midsize MRD splits the difference between duty and carry, pairing a 4-inch barrel with a shortened grip that conceals far better than a full-size gun while keeping a full firing grip for most hands. The MRD designation means the slide ships with FN's Low-Profile Optics Mounting System, which uses interchangeable plates to fit a wide range of red dots directly without adapters. Black finish, chambered in 9mm Luger.
