The FN 545 MRD COMP 45 brings the FN legacy of durability and practical design to a compact 45 ACP platform, blending an auto-indexing FN compensator and a 4.43" barrel to tame recoil and keep follow-up shots on target for home defense, duty carry, and range work; this striker-fired, optic-ready pistol features a crisp trigger, fully ambidextrous magazine release and slide stop lever, interchangeable backstraps for customizable ergonomics, and a 15+1 capacity that delivers serious stopping power in a controllable package. The MRD series is engineered for fast target acquisition with four MRD mounting plates included to accept popular red dot optics, while the serrated slide and no-manual-safety layout prioritize speed and intuitive operation under stress. Built with a black frame and black slide, the pistol ships with a locking device and zippered case for secure transport, and it requires an FFL transfer. Whether youre a law enforcement officer, competitive shooter, or experienced hunter looking for a compact .45 for defensive roles, the FN 545 MRD COMP 45 offers rugged construction, practical ergonomics, and accessory-ready features that address real-world shooting scenarios.
