About this product

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. The pistol ships with two magazines and an accessory rail for lights or lasers, making it suitable for duty use, range work, and serious carry considerations where a larger-frame .45 is appropriate.
