What It Does
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 that yield a clean, consistent single-action style trigger break while providing a smooth stack-free double-action. The matched sear and hammer engagement surfaces eliminate the need for any polishing or stoning. Please Note: We do NOT recommend using an extended firing pin. Only use the factory firing pin.



Expected Results
– Direct replacement for the factory hammer and sear
– Delivers a clean, consistent single-action style trigger break while providing a smooth stack-free double action
– Approximately 6 lb. DA with 4 lb. SA using Carry Mainspring
– Approximately 5 lb. DA with 3.5 SA using Competition Mainspring
– Easy to install
