The modern duty pistol must balance stopping power, ergonomics, and flexibility for optics. For shooters who want a full-size, striker-fired handgun built around the classic .45 ACP cartridge while remaining optics-ready, this platform delivers a thoughtful mix of mechanical reliability and sighting options.
FN 545 MRD [BLK] is the successor to FN’s FNS series and brings the .45 ACP into a chassis designed around optics. The pistol uses FN’s patented Low-Profile Optics Mounting System to accept more than 10 aftermarket red dot types via interchangeable adapter plates, and it ships with four optic mounting plates to get you on target quickly. It also comes with suppressor-height sights for easy co-witness when an optic is mounted. Shop this product

Design and optics integration
The FN 545 MRD [BLK] combines a familiar striker-fired cadence with a purpose-built optics platform. The Low-Profile Optics Mounting System reduces overall sight height while allowing compatibility with a wide array of red dots through supplied adapter plates. The suppressor-height sights provide a reliable iron sight option that co-witnesses with most optics, preserving a fast backup option if needed.
Ergonomics and control
Chambered in .45 ACP, the pistol offers the terminal performance many users prefer for defensive roles while maintaining manageable recoil through an ergonomically contoured grip and two included interchangeable backstraps. The package includes two 15-round magazines, offering significant capacity for a full-size .45 platform without sacrificing shootability.
Included accessories and value
FN packaged this model with a premium zippered case, two frame backstraps for fit customization, and four optic mounting plates so you can mount several red dots without extra purchases. At a price of $807.99, the set is positioned to give shooters a ready-to-use optics-capable .45 ACP out of the box. View product details and pricing
