This Action Enhancement Kit is a drop-in trigger system for the CZ 75 B (thumb safety models only). It addresses the wide gap between double-action and single-action pull weights, reducing the difference to approximately 2 lbs. The hammer and sear feature matched Apex-engineered single-action engagement surfaces, eliminating the need for polishing or stoning. Use with the factory firing pin only — extended firing pins are not recommended.

Frequently Asked Questions
Will this work in a CZ 75 SP-01?
Only if your SP-01 has a thumb safety (manual safety model). This kit is not compatible with decocker-equipped SP-01 Tactical pistols.
Why can’t I use an extended firing pin?
The kit’s hammer and sear geometry is tuned for factory firing pin length. Extended pins may cause primer drag or light-strike issues. Use only factory CZ 75 firing pins.
What’s the difference between the two mainspring options?
Carry Mainspring yields ~7 lb. DA / ~5 lb. SA — suited for defensive use. Competition Mainspring drops to ~6 lb. DA / ~4.5 lb. SA for range or match use. Both springs are included.
