Apex Tactical Action Enhancement Kit for CZ 75B

If you’re running a CZ 75B with a thumb safety, you already know the factory trigger has a split personality—heavy on the first double-action pull, then a lighter single-action for the follow-ups. That gap can throw off your rhythm, especially if you’re shooting in competition or just want consistency at the range. Here at Tucson Arms, we see a lot of guys trying to smooth that out with polish jobs or aftermarket parts that don’t quite fit. The Apex Tactical Action Enhancement Kit is the fix that actually works, no guesswork.

Apex, the manufacturer, designed this kit specifically for CZ 75B series pistols with thumb safeties. It comes with a matched hammer and sear set—meaning the engagement surfaces are cut to work together from the box. No stoning, no filing, no sending it off to a gunsmith in Phoenix. You get a clean, consistent single-action break and a smooth, stack-free double-action pull. The big win here is that it cuts the difference between first-shot DA and follow-up SA down to about two pounds. That’s a night-and-day improvement for practical shooting out in the desert heat or at an indoor range here in Tucson.

Inside the box, you get an Apex Performance Hammer and a Performance Matched Sear, both for thumb-safety models. For springs, Apex includes a Duty/Carry mainspring, a Competition mainspring, and a Reduced Power Firing Pin Spring—so you can tune the pull weight depending on whether you’re carrying or competing. There’s also two replacement hammer pins. The finish is black, and the hammer is exposed type, same as factory. It’s sold as a hammer and spring kit, model name Action Enhancement.

Price is $181.50. That’s a solid deal for what you’re getting—engineered parts that drop in and perform without hand-fitting. Tucson Arms is a licensed FFL dealer right here in Tucson, Arizona, and we ship to all 50 states. If you’ve got a CZ 75B with a thumb safety and want a trigger that feels like it was built by someone who actually shoots, this is the kit.
