The 4.25 in barrel is cold hammer-forged and non-threaded, with a recessed crown. The striker-fired action uses a flat-faced trigger with an integral safety tab, and the pistol incorporates a trigger safety.
Ergonomics and setup include interchangeable backstraps (spare included) and ambidextrous slide stop levers. A 4-slot Picatinny/M1913 accessory rail on the frame supports common white lights or lasers. Standard-capacity magazines provide a 15+1 configuration, and two steel magazines are included.
Finished in matching FDE on the slide and frame, this FN 545 MRD is a recent-release variant made in the USA and marked 'FN COLUMBIA, SC USA.' The configuration delivers the FN 545 series feature set in a full-size .45 ACP package with optics-ready capability and factory mounting hardware.
