The FN 545 Tactical pistol in .45 ACP with a 4.71-inch barrel and black finish (brand part no. 66101383) delivers a full-size, striker-fired duty platform in .45 ACP with genuinely high magazine capacity for the chambering. FN America / FN Herstal cuts the slide optic-ready and serrated, and suppressor-height night sights stay usable even with a red dot mounted. An ambidextrous slide release supports shooters of either hand dominance, and the pistol ships with one 15-round and one 18-round magazine, giving flexibility between concealment and maximum capacity. Among high-capacity .45 ACP semi-auto handguns, this 545 Tactical configuration favors duty and home-defense shooters who want .45-caliber stopping power with modern capacity.
