The Apex Tactical Action Enhancement Trigger for Glock® is a direct drop-in replacement of the factory polymer trigger and reduces pre-travel, overall trigger travel, and trigger reset, provides a smooth uptake and reset while delivering a crisp trigger break.
Trigger Only without trigger bar works in nearly all current Glock® model pistols including the G43. The trigger is NOT designed to function in the narrower frame of the model 42. Not for use with a Gen 4 Trigger Bar.
