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

Description

The Action Enhancement Kit from Apex Tactical is built specifically for the CZ 75 B with thumb safety. It replaces the factory hammer and sear with precision-matched components that reduce the gap between your first double-action pull and follow-up single-action shots. The result is a predictable, repeatable trigger that works reliably in the high-dust, dry-heat conditions common across Arizona.

For shooters running suppressed pistols in the desert, this kit keeps the factory firing pin in place. Do not use an extended firing pin with this setup. The stock firing pin is required for reliable primer ignition and safe operation with your suppressor attached.

The hammer and sear come with matched engagement surfaces engineered by Apex. No polishing, stoning, or hand-fitting is needed. This is a direct drop-in replacement that installs in minutes with basic tools.

Key performance numbers using the included mainsprings:

• Carry mainspring: Approximately 7 lb. double-action, 5 lb. single-action
• Competition mainspring: Approximately 6 lb. double-action, 4.5 lb. single-action

The single-action break is clean and consistent, with no creep or stacking in the double-action stroke. This lets you shoot faster and more accurately from the holster and during follow-up shots.

Real benefits for the desert shooter:

• Dust tolerance: The matched engagement surfaces resist debris intrusion better than hand-polished parts. Less carbon and grit buildup means your trigger stays consistent round after round.
• Heat stability: The kit maintains its pull weights even after extended strings of fire in 110°F+ conditions. No spring fatigue or trigger weight drift.
• Suppressor-ready: By retaining the factory firing pin, you avoid light primer strikes common with extended pins when running a can. The reduced trigger weight also makes it easier to shoot accurately with the added mass and gas blowback of a suppressor.
• No gunsmith required: Drop it in yourself in under 30 minutes. No fitting, no filing, no trip to a shop.

Fitment: Fits CZ 75 B pistols with thumb safety only. Not compatible with decocker models, CZ 75 Compact, CZ 85, or CZ Shadow variants. The kit works with both steel-frame and polymer-frame CZ 75 B pistols as long as they use the standard thumb safety configuration.

Price: $165. Add this kit to a CZ 75 B and you get a trigger that competes with custom shop pistols
