APEX Tactical Specialties Action Enhancement Kit for CZ 75 B - Black (Model 116142)

The APEX Tactical Specialties Action Enhancement Kit for CZ 75 B delivers a noticeable trigger upgrade for shooters who want consistency and control from their CZ pistol. If you've shot the factory CZ-75 B and noticed the gap between the double-action and single-action pull weights, this kit closes that gap—sometimes by as much as 2 pounds. The result is smoother transitions between shots and more predictable trigger performance, whether you're training at the range or carrying for defense.

This is a direct-replacement upgrade: the kit includes a precision-machined hammer and sear engineered to work together without modification. The sear and hammer engagement surfaces are matched for a clean single-action break and a smooth, stack-free double-action pull that stays consistent throughout the firing stroke. No stoning or fitting is required—drop them in and you're done. You get to choose your mainspring: pair it with the Carry Mainspring for a 7-pound double-action and 5-pound single-action, or go with the Competition Mainspring for a lighter 6-pound double-action and 4.5-pound single-action.

The APEX kit is built for the standard CZ-75 B frame; it does not fit decocker or Omega models, so verify your platform before ordering. If you run a working CZ pistol and want to reduce trigger confusion without replacing the entire gun, this is a focused, proven upgrade from a shop that knows CZ internals.
