Action Enhancement Kit for Glock® - Gen 3/4
About this product
If you own a Gen 3 or Gen 4 Glock® and want a trigger that feels like it was custom-fitted to your hand, the Apex Action Enhancement Kit is one of the best upgrades you can make. This kit is built around the Apex Action trigger system, which replaces the factory trigger bar, connector, and striker block with precision-machined parts that reduce take-up, overtravel, and reset distance. At $140, it’s a straightforward way to improve accuracy and control without sending your pistol to a gunsmith.

Key Features
- Reduced Trigger Travel – The kit cuts pre-travel by 40% compared to stock, so you spend less time pulling and more time on target. That means faster follow-up shots in defensive or competition scenarios.
- Crisp 4.5 lb Trigger Pull – According to Apex specs, the kit delivers a clean 4.5-pound break with no creep or grit. This weight balances safety with speed, making it ideal for everyday carry or range use.
- Short Positive Reset – The reset is dramatically shortened and tactile, so you feel and hear exactly when the trigger is ready to fire again. No guessing, no overtravel.
- Drop-In Installation – No fitting, filing, or drilling required. You can install this kit in about 20 minutes with basic hand tools—no gunsmith needed.
- Duty-Grade Reliability – All internal parts are made from hardened steel with a black nitride finish that resists wear and corrosion. Apex has been making trusted parts for law enforcement and military for over 15 years.
Who It’s For
This kit is for Glock® owners who shoot regularly and want a better trigger without the cost or wait of a custom build. It’s perfect for concealed carriers who need a safe, predictable trigger pull, competition shooters who want a faster reset, and anyone who finds the factory Glock® trigger too spongy or heavy. If you’ve ever thought, “I wish my Glock® shot like a $2,000 pistol,” this gets you close for under $150.
Pros & Cons
- Pros: Drop-in installation, noticeable improvement in trigger feel, durable finish, backed by Apex’s reputation, affordable compared to full trigger swaps.
- Cons: The trigger shoe is polymer, not aluminum—some shooters prefer an all-metal shoe for a more premium feel. Also, the 4.5 lb pull may still feel heavy for competition shooters who want 3.5 lb or lighter.
Comparison: Apex vs. Zev Technologies vs. Timney
| Feature | Apex Action Enhancement Kit | Zev Technologies Pro Trigger | Timney Alpha Glock Trigger |

The Apex kit gives you the best balance of price, reliability, and ease of install. Zev offers a lighter pull but costs more and may need fitting. Timney is lighter still but pricier and more complex to install. For most Glock® owners, the Apex is the smart choice.
Frequently Asked Questions
Will this kit fit my Glock® 19 Gen 4?
Yes, the Apex Action Enhancement Kit is compatible with all Gen 3 and Gen 4 Glock® models listed in the specs above, including the Glock® 19 Gen 4. It also fits the 17, 22, 23, 26, 34, and many others.
Do I need to modify my Glock® frame or slide for installation?
No modification is needed. This is a true drop-in kit. You simply remove your factory trigger assembly, drop in the Apex parts, and reassemble. No filing, drilling, or Dremel work required.
Is this kit safe for concealed carry?
Yes. The 4.5 lb trigger pull is heavier than a competition trigger, which helps prevent accidental discharges under stress. The kit also retains all factory safety features, including the trigger safety blade and firing pin block.
Does this kit work with aftermarket slides or barrels?
Yes, it works with any Glock® Gen 3/4 frame, regardless of slide or barrel brand. The kit only replaces internal trigger components, so compatibility is not affected by aftermarket slides or barrels.
