Action Enhancement Kit for CZ 75 B (thumb safety models only)

Description

The Apex Action Enhancement Kit for the CZ 75 B is built for shooters who want a more predictable trigger without losing reliability. This kit directly addresses the common complaint about the large weight gap between the double-action first shot and the single-action follow-ups, reducing that difference to roughly 2 pounds. Instead of polishing or stoning parts, the hammer and sear feature matching Apex engineered single-action engagement surfaces that work together right out of the box.

For daily carry or home defense, the kit provides a clean, consistent single-action style trigger break with a smooth, stack-free double-action pull. Using the included Carry Mainspring, you get approximately a 7 lb. double-action pull and a 5 lb. single-action pull. If you prefer a lighter setup for range use or competition, swap to the Competition Mainspring for approximately a 6 lb. double-action and 4.5 lb. single-action pull. Both options deliver a noticeable improvement over the factory trigger without introducing mush or creep.

Important fitment note: This kit is specifically designed for CZ 75 B pistols with thumb safeties. It does not fit decocker models or the CZ 75 BD. Installation is straightforward — this is a direct drop-in replacement with no fitting required. You do not need to modify the frame, trigger bar, or trigger itself. The kit includes the hammer, sear, and both mainsprings.

Critical safety guidance: We strongly recommend using only the factory firing pin with this kit. Do not install an extended firing pin. The kit is engineered to work with the factory pin for reliable ignition and safe primer contact. Using an extended firing pin risks light strikes or unintended discharge.
