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.

    Beyond happy with my cerakoted 509 trigger from Legion. They did an amazing job. Very quality coating and very quick turn around time.
