The Apex Action Enhancement Kit for the CZ Shadow 2 pistol is designed to reduce the large difference in trigger pull weight that exists between the double-action first shot and the subsequent single-action shots to approximately 2 pounds. The hammer and sear have matching Apex engineered single-action engagement surfaces which eliminates the need for any polishing or stoning. Please Note: We do NOT recommend using an extended firing pin. Only use the factory firing pin.
