The Apex Action Enhancement Kit for the FN 509 model pistols is a direct dropin replacement of the factory polymer trigger trigger bar and sear. The patentpending Apex design reduces trigger pull weight to give you an approx. pull weight in the 5.5 lbs range. Trigger travel is also reduced including pretravel overtravel overall trigger travel and trigger reset distance. It provides a smooth uptake while delivering a crisp trigger break.
