Action Enhancement Kit for Glock® – Gen 3/4

Action Enhancement Kit – Glock® Gen 3/4

This drop-in kit reduces trigger pull weight by approximately 1 lb. while shortening pre-travel, overall travel, and reset distance. It replaces the factory trigger mechanism bar, safety plunger, and connector with components that deliver a smoother uptake, a crisp break, and a shorter, positive reset. The center-mounted pivoting safety maintains factory safety values. No fitting required – direct drop-in replacement.

FAQ

Will this work with my Gen 5 Glock?

No. This kit is designed for Gen 3 and Gen 4 frames only. Gen 5 requires a different trigger system.

Does this include a new trigger shoe, or just the bar?

This kit includes the complete Apex Action Enhancement Trigger with a Gen 3 trigger bar, the Ultimate Safety Plunger, and the Performance Connector. It is a full drop-in assembly – not just a bar or shoe.

Will this reduce trigger pull below 4 lbs.?

Typical pull reduction is ~1 lb. from factory weight. Final pull weight depends on your pistol’s spring configuration (striker spring, trigger spring). For lighter pulls, pair with a reduced-power striker spring – verify reliable primer ignition first.
