APEX Action Enhancement Trigger Kit for FN 509

The Apex Action Enhancement Kit for the FN 509 model pistols is a direct drop-in replacement of the factory polymer trigger, trigger bar and sear. The patent pending Apex design reduces trigger pull weight to give you an approx. pull weight in the 5.5 lbs range.
