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

This Action Enhancement Kit for the CZ 75 B (thumb safety models only) is a direct drop-in upgrade that cuts the heavy gap between your first double-action pull and follow-up single-action shots down to roughly 2 lbs. No filing, no polishing, no stoning — just a clean swap that gives you a consistent trigger break every time.

• Drop-in fit, no gunsmithing needed. The hammer and sear come with matching Apex engagement surfaces already engineered in. You don’t have to touch a file or a stone. Remove the old parts, install these, and you’re done.
• Reduces the DA/SA gap to about 2 lbs. Stock CZ 75 B triggers often have a big jump from the first heavy pull to the lighter follow-ups. This kit tightens that spread so your double-action and single-action pulls feel closer together — less adjustment between shots.
• Two spring options for pull weight. Use the Carry Mainspring for roughly 7 lbs DA / 5 lbs SA. Swap to the Competition Mainspring for about 6 lbs DA / 4.5 lbs SA. Pick the setup that fits your shooting — defensive or range work.
• Smooth double-action, crisp single-action. The double-action stroke is stack-free — no gritty buildup or sudden wall. The single-action break is clean and consistent, like a good single-action trigger, without the mush or creep you get from stock parts.
• Use factory firing pin only. Do not install an extended firing pin with this kit. Stick with the factory pin for reliable function and safe operation.

Specs & Fitment:

• Fits CZ 75 B pistols with thumb safety (does not fit decocker models or safety models with frame-mounted safety).
• Kit includes: Apex hammer, Apex sear, carry mainspring, competition mainspring, and installation pins.
• Pull weights are approximate and based on factory CZ 75 B recoil spring and trigger return spring. Results may vary slightly with different spring combinations.
• Direct replacement — no fitting, no polishing, no stoning required.

Why this kit works for you:
You want a better trigger without sending your gun to a smith or buying a whole new pistol. This kit gives you a repeatable, predictable pull that makes your CZ shoot smoother and more accurately — whether you’re burning through bulk ammo at the range or carrying for personal defense. At
