Introducing the all-new FN 545 Tactical. Forged to defend your homefront with an unrivaled 18+1 capacity, red-dot-ready slide and a crisp trigger. Leave nothing to chance with 18+1 rounds, setting a new standard capacity in .45 ACP. Suppressor-ready, with a threaded barrel and co-witness tritium night sights, this industry-first pistol is upgraded with the proven ergonomics of the FN 509 Tactical. Shooters can mount their favorite red dot optic in minutes, adding pinpoint control on command. Complete with the high-endurance striker and crisp, approximately 6lb. trigger pull, the FN 545 Tactical is what other big bore pistols want to be when they grow up.
