The MRD configuration provides an optics-ready slide with FN's Low-Profile Optics-Mounting System and a removable cover plate. It accepts major micro red dot footprints, and the blacked-out iron sights are co-witness capable for a clear, uncluttered sight picture.
The 4.1-inch flush-fit barrel is cold hammer-forged with a recessed crown and a polished feed ramp. This setup pairs .45 ACP chambering with a compact barrel length while maintaining a 15+1 capacity using steel double-stack magazines.
Controls are fully ambidextrous, including the slide stop and magazine release, with an ambidextrous design that supports either hand. The striker-fired system features a flat-faced trigger and a trigger safety for a consistent, modern trigger feel.
The slide wears a matte black finish with front and rear cocking serrations, and it is marked 545 with FN branding. The polymer frame, also matte black, includes a textured grip with an indexing pad, FN medallions, and a lanyard hole. A 4-slot Picatinny/MIL-STD-1913 rail on the dustcover supports lights or other accessories.
Chamber and slide are marked .45 ACP, and this pistol is manufactured in Columbia, South Carolina, USA. The package includes two 15-round magazines and the owner's manual; no cable lock is included.
