Certified Special ACE Trigger System for Glock

A Revolution in Glock Performance

The ACE Trigger System for Glock pistols is a breakthrough in trigger performance, reliability, and safety. This is not just an upgrade — it redefines what your Glock is capable of.

Why You’ll Love It

• Unmatched Performance Gains: The ACE Trigger System delivers the largest margin of improvement of any product we've ever launched.
• Fully Tunable Feel: Adjust break weight and reset to your exact preferences.
• 1911-Inspired Precision: Designed to feel like a high-end 1911, with a pull weight range of 2.5–6.0 lbs.
• USPSA approved, and permitted in IPSC Standard, Optics, and Open divisions.

Engineered for a New Standard

The ACE Trigger System completely reimagines Glock trigger mechanics by eliminating the parasitic movements that plague standard designs.

Key Design Innovations:

• Separate Disconnect Module (backplate) and Sear Module — not a one-piece connector
• True pivoting firing pin safety eliminates grit and drag
• Patented Zero Creep Technology™ for an exceptionally crisp break
• CLKR Technology™ lets you fine-tune pull weight with precision and confidence

Fully Modular. Fully Adjustable.

The ACE Trigger System includes three modular components:

1. Lever Module
2. Sear Module (with CLKR Technology™)
3. Disconnect Module (backplate)

Customize to your liking:

• Ships with heavy lever take-up spring pre-installed
• Includes light take-up spring and plunger safety spring
• Combine spring sets and use the CLKR screw to dial in your ideal feel and set your pull weight between 2.5–6.0 lbs

Built to Perform. Built to Last.

Every ACE Trigger System is built using premium materials and protective coatings, chosen for durability in harsh conditions and extensive use with no degradation in reliability.

• Zero Creep Technology™ is contamination-resistant and built for long service life
• Field-tested across high round counts and diverse environments

Safety-First Design

Performance without compromise. The Certified Special features a pivot safety on a monolithic trigger lever for a clean engagement, encouraging consistent trigger breaks.

Main features:

1)       Frame-decoupled safety – We engineered the lever and transfer bar to provide the safety function independent of frame tolerances.

2)      Redesigned safety stop – Updated geometry of the trigger lever broadens compatibility across real-world frame tolerances.

3)      TMDE pad – A small feature on the lever module that helps range officers verify the lever safety is functioning properly.

The trigger's Disconnect Module (backplate) also includes a relief pocket that increases clearance to the striker under extreme shock conditions.
