Leave nothing to chance with 15 rounds, setting a new standard capacity in .45 ACP. 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.The FN Compensator significantly decreases felt recoil and features v-style ports on either side that vector gases and flash out of the user's field of view. The result is a shooting experience that is flatter and more controlled, allowing users to maintain a consistent sight picture from shot to shot. Machined from stainless steel and coated with a robust PVD finish, the compensator is extremely durable and is designed to withstand hard use across standard and self-defense loads for the widest degree of compatibility, while still utilizing the factory FN 545 recoil spring.
