FN's 545 brings the company's modern striker-fired design language to .45 ACP, with an optics-ready slide, aggressive cocking serrations, and interchangeable backstraps to fit a wide range of hands around what is inherently a large-bore grip. This MRD configuration wears a 4.43-inch barrel and black finish.

FN engineered the 500 series with high-capacity magazines and a low bore axis to keep a big cartridge manageable, and the result is a duty-size .45 that shoots flatter and holds more rounds than the .45s most shooters grew up with.
