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 approximately 5.5lbs.
Trigger travel is also reduced, including pre-travel, over-travel (by 50%), overall trigger travel, and trigger reset distance.
The Action Enhancement Kit provides a smooth uptake and reset while delivering a crisp trigger break.
