Description
The CZ 75 B already ships with one of the better factory triggers out there, but that first double-action pull sitting way heavier than every single-action shot after it is a real pain point. This Apex Action Enhancement Kit tackles exactly that. It drops in a matched Performance Hammer and Sear that bring the difference between your DA first shot and your SA follow-ups down to roughly 2 pounds, so the trigger feels a whole lot more predictable from the first round to the last.
The hammer and sear come with Apex's engineered single-action engagement surfaces already matched at the factory, which means no polishing, stoning, or fitting on your end. You get a clean, consistent single-action break paired with a smooth, stack-free double-action pull. That combination is what makes this kit a favorite for anyone running a CZ hard, whether it's a range gun, a carry piece, or a competition setup.
Tuning the CZ 75B Trigger to Your Style
Apex includes two mainsprings so you can dial in the pull weight. The Duty/Carry mainspring (purple) lands you around 7 lb DA with a 5 lb SA break, while the Competition mainspring (silver) lightens things to about 6 lb DA with a 4.5 lb SA. Swap between them depending on what you're doing that weekend. A reduced power firing pin return spring and a set of two replacement hammer pins round out the package.
What This Apex Kit Fits
This is the thumb safety version, built for CZ 75 B manual safety models in 9mm and .40 S&W, including the High Polish Stainless, Matte Stainless, the SP-01 (not the Tactical), and the CZ 75 Compact. It is not meant for decocker or Omega trigger system pistols, so double-check your frame before ordering. Installation is straightforward for anyone comfortable working on their pistol, though having a gunsmith handle it is never a bad call. One tip worth repeating from Apex: stick with your factory firing pin and skip any extended versions.

Frequently Asked Questions
Will this Apex kit fit my CZ 75 B?
This version is made for CZ 75 B manual thumb safety models in 9mm and .40 S&W. That includes the High Polish Stainless, Matte Stainless, SP-01 (not the Tactical), and the CZ 75 Compact. It will not work on decocker or Omega trigger system pistols, so confirm your frame type before ordering.
Do I need to polish or stone the hammer and sear before installing?
No. Apex matches the single-action engagement surfaces on the hammer and sear at the factory, so there's no fitting, polishing, or stoning required. It's a direct replacement for your factory hammer and sear.
What's the difference between the two mainsprings in the kit?
The Duty/Carry mainspring (purple) gives you roughly 7 lb DA with a 5 lb SA break for a firmer, more defensive-minded pull. The Competition mainspring (silver) lightens things to about 6 lb DA with a 4.5 lb SA. You can swap between them to match how you're using the gun.
Can I install the Apex Action Enhancement Kit myself?
If you're comfortable detail-stripping your CZ, the install is manageable at home. That said, having a qualified gunsmith handle it is a smart move if you're unsure. One important note from Apex: always run the factory firing pin and avoid any extended firing pin with this kit.
