FN 545 MRD .45 ACP – FN America / FN Herstal

The FN 545 MRD is a semi-automatic, striker-fired pistol engineered for controlled range performance and duty use. Its optics-ready slide and included Holosun 407C make it suitable for shooters who prefer a red dot-equipped platform for target work or training.

Built on a Flat Dark Earth polymer frame with interchangeable backstraps, the pistol pairs an ergonomically enhanced grip with a steel slide featuring front and rear serrations. The cold hammer-forged steel barrel and recessed crown provide a durable foundation while the low-profile optics mounting system allows rapid sighting with co-witnessed iron sights.
