The FN 545 Tactical pistol in .45 ACP with a threaded barrel and black finish (brand part no. 66101385) delivers serious stopping power in a duty-capable, suppressor-ready platform. FN America builds the pistol with a 10+1 capacity, a 4.71-inch barrel threaded .578×28 for compensators and suppressors, and a double-action-only trigger for consistent pull weight on every shot. Night sights sit at suppressor height for use with a can mounted, and the optic-cut, serrated slide with fully ambidextrous controls rounds out the package. Two magazines ship with the pistol. Among suppressor-ready semi-auto handguns, this FN 545 Tactical configuration favors shooters who want a full-power .45 ACP platform built for optics and suppressors.
