Apex Tactical Specialties 102173BLU Action Enhancement Kit Blue - Fits Glock Gen 3/4

The Apex Tactical Specialties Action Enhancement Kit is a complete drop-in trigger upgrade built for Glock Gen 3 and Gen 4 pistols. This 102173BLU kit ties together the Apex Action Enhancement Trigger, a Gen 3 trigger bar, an Apex Ultimate Safety Plunger, and an Apex Performance Connector for a one-piece, direct-replacement solution that drops right into the factory housing with no fitting required.

The trigger shoe is machined from aluminum and finished in a distinctive blue color, paired with a nickel Ultimate Safety Plunger and the Performance Connector. Together these components reduce trigger over-travel and reset distance while delivering a smoother uptake and a crisp, clean break compared to the factory polymer trigger.

This kit is designed for installation in standard-frame Glock Gen 3 and Gen 4 models, including the G17, G17L, G19, G22, G23, and G24. It is not intended for Gen 5 slides, which use a separate Apex kit.

Apex Tactical Specialties is one of the leading manufacturers of drop-in aftermarket performance parts for popular pistol platforms, and the Action Enhancement Kit is a straightforward upgrade that gives Glock Gen 3/4 owners a noticeably improved factory-style trigger feel without permanent modification.
