TriggerTech Competitive Special ACE Trigger System for Glock Gen 1-5

The TriggerTech Competitive Special ACE Trigger System for Glock Gen 1-5 is a fully modular, adjustable drop-in trigger designed for shooters who want precision control and a genuinely crisp break. Unlike the single-piece connector found in stock Glock triggers, the ACE system separates the disconnect and sear modules to eliminate the parasitic movements and creep that come standard on factory Glock pistols. If you shoot competitively, run drills at the range, or demand consistency from your carry gun, this is a serious upgrade from a gunsmith who understands trigger work.

What sets the ACE apart is its tunability. The system ships with a heavy lever take-up spring pre-installed and includes a light take-up spring and light safety plunger spring, so you can mix and match to dial in your exact feel. The proprietary CLKR adjustment screw lets you set pull weight anywhere from 2.5 to 6.0 lbs without guesswork. The enveloped lever safety—developed over three years of testing—delivers a smooth, monolithic trigger face while maintaining full function and safety. Zero Creep Technology resists contamination and holds up through high round counts and harsh environments.

The ACE works across all five Glock generations (Gen 1 through Gen 5) in 9mm and .40 S&W standard frames. Gen 5 owners will need to remove a small tab on the frame per the included instructions. Because this is a precision trigger system, installation should be handled by an experienced gunsmith—improper assembly can compromise safety.
