Having a better trigger in your go-to competition or duty pistol makes all the difference when it comes to putting rounds right where you want them. This Apex Tactical Action Enhancement Kit is designed for the FN 509 and comes with a curved trigger design while also enhancing other elements of the trigger press. Designed as a direct, drop-in replacement for the OEM trigger, trigger bar and sear, the Apex Tactical Action Enhancement Kit reduces trigger-pull weight down to about 5.5 pounds. Trigger travel distance is also reduced, as the kit cuts down on pre-travel and overtravel by 50 percent. The trigger pull itself is also improved, providing users with a smoother, easier press that finishes with a crisp break. This Apex Tactical Action Enhancement Kit ensures that all factory safety elements are maintained, and the kit fits the FN 509, 509 Midsize, 509 Tactical and the FN FNS-c.
