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 and IPSC approved
  • Engineered with everyday carry and duty applications in mind, the Legacy Special has demonstrated strong drop safety and rough-handling performance, and was able to pass applicable SAAMI drop test protocols in internal testing with a wide margin of safety when set to 3.5 lbs
  • Trigger configurations below 3.5 lbs are intended for controlled competition and range use only and are not recommended for carry or duty applications

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

The Legacy Special gives users the familiarity of the Glock style safety blade, without compromising the performance you expect from TriggerTech.

Main features:

1)      Safety Blade – Maintains the OEM Glock style safety blade

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

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

4)      Drop Tested – Extensively tested on compatible platforms, the Legacy Special was engineered to deliver exceptional durability, drop safety, and rough-handling performance, relative to SAAMI drop test protocols

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

What’s Included

  • Legacy Special ACE Trigger System (3 Modules)
  • Light + Heavy Lever Take-Up Springs
  • Light Safety Plunger Spring
  • Pin Tool
  • 5/64" Allen Key

Great buy
Size: 2 Count (Pack of 1), Style: Pack of 2
Easy to track balls. My dog loves them and I like that they whistle when you throw them cause some times my dog loses track of it in the air. This helps because they can hear where it's going. Will buy again.

My Dog's Favorite Balls
Size: 2 Count (Pack of 1), Style: Pack of 2
My dogs love these balls and won't play with any others. My lab has to carry the orange ball and track and retrieve the blue one. We have a system!

Our perfect chew toy for a relentless chewer!
Size: 2 Count (Pack of 1), Style: Pack of 2
We have looked high and low for a ball that our Australian Shepherd couldn't destroy. Read on to find out why we are sticking with this one. We've used other Chuckit! products in the past to mixed degrees of success. We absolutely love the ring fetch toy, though the dog can destroy those rings in a couple days. We tried other "nearly indestructible" balls only to have to throw them away within a couple days because our dog had destroyed them and left small pieces around the house for the baby to find. We have been COMPLETELY satisfied by these balls. They fit with the Chuckit! stick, which is a great bonus, but the most important thing is the dog hasn't been able to get pieces torn out of them. His orange one is his "indoor toy" and he's been going to town on it for weeks without any indication of wear. We periodically inspect it and are always floored to see that it's generally in the same condition as when we gave it to him. The orange color did fade a little when he left it outside for a few days in the sun, but considering how well it works otherwise, this didn't concern us at all. The "whistling" aspect of this ball is... well, an interesting gimmick but I wouldn't buy it if that's what you're interested in. Sometimes it makes noise in flight, other times it doesn't. We don't care. He chews it until he's tired of it (which is usually hours) and it squeaks and squorks on his teeth which keeps him happy as a clam. We honestly didn't think we'd find a ball that could keep up with his chewing, but this one has been phenomenal. We cannot recommend it enough!

So Far So Good
I adopted a young adult dog less than 2 weeks ago. She had spent over 12 hours a day in a crate and has excessive energy and anxiety built up. She is a strong chewer. So far, out of 6 toys, this is the only one still in one piece. It appears sturdy and extra bouncy. So much better than regular tennis balls.

My dogs favorite!
My dogs love these! They will play all day if you'd let them, these balls are their favorites. I use the chuck-it handle and they get tons of exercise in the big yard!
