The FN 545 Tactical pistol in flat dark earth PVD with an 18+1 capacity (brand part no. 66101384) sets a new standard capacity in .45 ACP, giving shooters a high-round-count option in a caliber traditionally limited to single-digit magazines. FN America fits a suppressor-ready threaded barrel with a target crown, co-witness tritium night sights, and a high-endurance striker paired with a crisp, approximately 6-pound trigger pull. A loaded chamber indicator, ambidextrous slide stop lever, and ambidextrous magazine release round out the controls, and the kit includes two magazines, two interchangeable backstraps, four MRD mounting plates, and a zippered case. Among high-capacity semi-auto handguns, this FN 545 Tactical configuration favors shooters who want maximum .45 ACP capacity with suppressor compatibility.
