FN's 545 is the .45 ACP member of the striker-fired family that started with the 509, and it brought a genuinely modern take to a cartridge that has mostly been served by older designs. FN drew on its military contract work for the ergonomics, with a low bore axis, aggressive but comfortable texturing, and fully ambidextrous controls.

The MRD designation means it ships optics-ready with FN's Low-Profile Optics Mounting System, which fits a wide range of red dots without proprietary plates for every sight. With a 4.1-inch barrel and a black finish, this is a duty-capable .45 in a package that carries better than most.
