This Action Enhancement Kit for the CZ 75 B (decocker models) reduces the factory trigger pull delta between double-action and single-action shots to approximately 2 lb. The hammer and sear ship with matched single-action engagement surfaces, so no polishing or stoning is required. Use factory firing pin only — extended firing pins are not recommended with this kit.

FAQ
Will this fit a CZ 75 B safety model?
No. This kit is specifically for decocker-only CZ 75 B frames. Safety models use a different sear geometry and will not accept these components.
Why can’t I use an extended firing pin with this kit?
The hammer geometry and spring rates in this kit are tuned for factory firing pin length. An extended pin can create unintended primer contact or light-strike issues. Stick with OEM.
Does this kit include springs?
Yes. Both the Carry Mainspring and Competition Mainspring are included, along with the hammer and sear. You choose which mainspring to install based on your preferred DA/SA balance.
