Comment: Cat H license. 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.



– 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

– Direct drop-in replacement, no fitting required



For use in the CZ Shadow 2 pistol only (no B series firing pin block). Will work in the Single Action (SA) versions of those guns with the manual thumb safety. Will work with CZ 75 SP-01 Shadow Target II.
