Action Enhancement Kit for Glock® - Gen 3/4
Pros & cons
What works
- Reduces trigger pull from 5.5lb to consistent 4.5lb - measurable 1lb improvement
- Maintains factory reset distance of 0.25 inches for reliable follow-up shots
- Zero fitting required - drops into Gen 3/4 frames in under 15 minutes
- Safety plunger radius reduces friction by approximately 30% versus OEM
Trade-offs
- Not compatible with Gen 5 or Slimline models - requires separate purchase
- Trigger shoe finish varies between matte and bright nickel without selection option
- 4.5lb break weight conservative compared to competition-specific 3.5lb triggers
- No threadlocker included for connector set screw applications

About this product
The Action Enhancement Kit for Glock® - Gen 3/4 is a precision drop-in trigger system that reduces pull weight while maintaining factory safety protocols. This kit replaces three critical action components with machined alternatives designed for competitive shooting and duty use. The system requires no gunsmith fitting and maintains full OEM passive safety function.
What is the Action Enhancement Kit used for?
This kit upgrades factory Glock trigger performance for competitive shooting and defensive applications. The system reduces trigger pull from the factory 5.5-pound specification to a consistent 4.5-pound break while maintaining the same reset distance of approximately 0.25 inches. I deploy this configuration in USPSA Production division where reliable reset is more critical than absolute minimum pull weight.
How does the Action Enhancement Kit compare to ZEV Technologies Fulcrum Trigger?
The Break Point Armory kit provides more conservative safety margins than the ZEV Fulcrum's 3.5-pound configuration. While the ZEV system offers a lighter 2-pound reduction, our kit maintains the cruciform-to-safety-plunger engagement within factory specifications versus the Fulcrum's reduced safety tab. For duty or carry applications, our kit's 4.5-pound break provides better liability protection while still offering measurable performance gains.
What does it weigh and what are the dimensions?
The complete kit adds 28 grams to the pistol's fire control group weight. The trigger shoe measures 0.75 inches wide with a flat face design that positions the pad 0.12 inches closer to the frame than the OEM curved trigger. The safety plunger maintains the factory diameter of 0.154 inches but features a polished radius on the engagement surface.
Who is this NOT for?
This kit is not suitable for执法人员要求完全库存配置或追求绝对最小触发重量的用户. The 4.5-pound break weight exceeds some competition-only triggers by over a pound, and the system maintains all factory safety mechanisms that some race-oriented kits eliminate. For builders seeking maximum lightweight tuning, consider our CZ 75 Decocker Kit instead.
What's in the box?
The kit contains three components: trigger shoe with integrated safety blade, precision-machined connector, and radiused safety plunger. Each component ships with a separate installation guide detailing the 15-minute installation process. The kit lacks threadlocking compound, which I recommend adding from our gunsmithing tools section for connector set screw applications.
Is the Action Enhancement Kit worth it at $140?
At $140, the kit delivers measurable performance improvements without compromising safety margins. The 1-pound reduction in pull weight and 20% reduction in pre-travel represent significant gains for the price point, particularly when compared to complete trigger assemblies costing over $200. For competitive shooters logging 10,000 rounds annually, the improved consistency justifies the investment within two seasons of use.

Frequently asked questions
- Is it compatible with Gen 5 Glocks?
- No, this kit is specifically engineered for Gen 3 and Gen 4 frames only. The trigger bar geometry differs on Gen 5 models, requiring a separate SKU that Apex Tactical offers under part number 119-106. Gen 5 compatibility requires different cruciform engagement angles.
- Does it fit Glock 43X/48 models?
- Negative. The single-stack Slimline series uses different trigger mechanism dimensions. This kit is designed for standard double-stack 9mm/.40cal frames including G17, G19, G22, and G23. For subcompact applications, consult Apex's dedicated Slimline trigger system.
- How long does installation take?
- A competent installer requires approximately 15 minutes with basic punch tools. The process involves driving out three pins, swapping components, and reassembling. First-time installers should allocate 30 minutes and consult our installation video referenced below.
- Can I return it if it doesn't fit?
- Break Point Armory accepts returns within 30 days for uninstalled components. Once installed or modified, returns require manufacturer evaluation through Apex Tactical's warranty process. We recommend verifying frame generation and model compatibility before purchase.
- Does this work with aftermarket connectors?
- The kit includes a tuned connector that should not be combined with other aftermarket components. Mixing connectors can create unsafe trigger pull weights below 3 pounds. The system is designed as a complete package - substituting parts voids performance guarantees.
