Description
The FN 545 MRD 45ACP NMS D 15RD BLK brings big-bore power into a package that handles like a much smaller gun. This is the factory-optics-ready version of FN’s proven 545 platform, chambered in .45 ACP with a 15-round magazine. It’s built for shooters who want stopping power without the usual bulk or recoil.

Key Features
- Factory optics cut – Why it matters: You can mount your favorite red dot sight in minutes with no gunsmithing. That means faster target acquisition and better accuracy right out of the box.
- Upgraded ergonomics – Why it matters: The grip angle and texture keep the gun locked in your hand. Less shifting under recoil means faster follow-up shots.
- High endurance striker – Why it matters: FN designed this striker to handle thousands of rounds without failure. It’s one less thing to worry about when you’re training or carrying.
- Crisp 6-lb. trigger pull – Why it matters: A clean break helps you stay on target. No grit, no creep — just a predictable pull that makes every shot count.
- 15-round magazine capacity – Why it matters: That’s two more rounds than most .45 ACP pistols. More ammo on tap without making the grip any bigger than it needs to be.
Who It’s For
This pistol is for the shooter who wants .45 ACP reliability in a modern, optics-ready platform. It fits home defense, range use, and duty carry. New gun owners will appreciate the manageable recoil and easy-to-learn trigger. Experienced shooters will like the factory cut and high capacity. It’s also a solid choice for anyone moving up from 9mm who wants more terminal performance without jumping to a revolver.
Pros and Cons
Pros
- Factory optics-ready with multiple mounting plates
- 15+1 rounds of .45 ACP
- Durable black nitride finish
- Low bore axis reduces muzzle flip

FAQ
Does the FN 545 MRD come with mounting plates for red dot sights?
Yes, the pistol includes multiple mounting plates to fit popular red dot footprints like Trijicon RMR, Holosun 407C/507C, and Leupold DeltaPoint Pro. You’ll need a screwdriver to swap plates, but no drilling or machining is required.
Is the FN 545 MRD compatible with standard FN 545 holsters?
Yes, the MRD version uses the same frame dimensions as the standard FN 545. Any holster made for the FN 545 will fit the MRD. Just make sure your holster has an open muzzle or accommodates suppressor-height sights if you plan to add them.
What is the magazine capacity of the FN 545 MRD?
The FN 545 MRD ships with two 15-round magazines. That’s standard for this model, and extra magazines are available separately through FN or aftermarket suppliers.
Is the FN 545 MRD suitable for concealed carry?
It’s on the larger side for everyday carry due to the 4.5-inch barrel and full-size grip. Many people do carry it in an OWB holster under a jacket. For deep concealment, a compact .45 like the FN 545 Compact might be a better fit.
