Glock Standard Frame Gen 1-5 – TriggerTech Special ACE Trigger System
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The TriggerTech Special ACE Trigger System is an adjustable two-stage trigger system for compatible standard-frame Glock Gen 1-5 pistols in 9mm and .40 S&W.
This is a premium trigger system, not a cheap shoe swap. It uses TriggerTech’s Zero Creep, TKR, and CLKR technologies, with adjustable pull weight from 2.5 to 6.0 lb. It also has major fitment and install notes, especially on Gen 5 frames.
