The Apex Tactical Action Enhancement Competition Trigger (brand part no. 119125) is a black drop-in trigger upgrade built specifically for the FN 509 pistol. Apex Tactical Specialties replaces the factory trigger, trigger bar, and sear as a matched set using its patent-pending Action Enhancement design, bringing pull weight down to approximately 5.5 pounds while shortening pre-travel, over-travel, and reset. The result is a smoother uptake and a crisper, more consistent break for competition or duty use, installed without gunsmith work.
