Apex Tactical 119113 Action Enhancement Black Drop-In Trigger Fits FN FNS CompactThe Apex Action Enhancement Kit for the FNS Compact 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. Trigger travel is also reduced, including pre travel, over travel, overall trigger travel, and trigger reset distance. It provides a smooth uptake while delivering a crisp trigger break.
