The Action Enhancement Kit for CZ P-10 pistols features the Apex Action Enhancement Trigger paired with an Apex Performance Disconnector and an Apex Slide Cover Plate. The kit is a direct drop-in replacement of the factory polymer trigger, disconnector and slide cover plate, and provides a reduction in pull weight from sub-4.0 lbs. (w/ Apex Performance Disconnector) to 5.5 lbs. (w/ CZ Factory Disconnector). Using the CZ Factory Disconnector provides a more defined trigger break at striker release (approx. 5.5 lbs.), while using the Apex Performance Disconnector provides light, smooth take-up and linear rolling trigger break at striker release (approx. sub-4.0 lbs.).
