Apex Tactical Action Enhancement Kit for Glock Gen 3 & Gen 4 - 9mm Luger, .40 S&W - Black Aluminum

The Apex Tactical Action Enhancement Kit for Glock Gen 3 & Gen 4 pistols is a drop-in trigger upgrade designed for shooters who want a measurably better trigger without replacing core components. Available for 9mm Luger and .40 S&W models, this kit swaps Glock's factory polymer trigger for a machined black aluminum unit that cuts trigger pull weight by about 1 pound while smoothing travel and sharpening reset feedback. Whether you're running drills at the range or competing in action matches, a refined trigger can tighten your splits and group consistency.

Apex engineered this kit to improve four core trigger qualities: it reduces overall travel distance, softens the pull stroke itself, delivers a cleaner break point, and provides more tactile feedback when the trigger resets. All factory safeties remain fully functional—Glock's drop safety, firing pin safety, and trigger safety are unchanged and still in place. That means this is a genuine upgrade, not a compromise.

Installation is straightforward for anyone comfortable field-stripping a Glock. The kit fits Gen 3 and Gen 4 models in the listed frame sizes (G17, G17L, G19, G22, G23, G24, G26, G27, G31, G32, G33, G34, G35). Note that this kit is not compatible with Gen 5 Glocks, which require different internal geometry.
