The FN 545 MRD Comp is a full-size, striker-fired pistol chambered in .45 ACP designed for reliable service and controllable performance. It incorporates an auto-indexing compensator to reduce muzzle rise, a stainless-steel slide with FN’s low-profile optics-mounting system, and a polymer frame with interchangeable backstraps for a tailored grip.
