Is it compatible with Glock 19 Gen 4?

Yes, full compatibility includes all Gen 3 and Gen 4 Glock models in 9mm, .40 S&W, and .357 SIG calibers, specifically the G17, G19, G22, G23, G31, and G32. It will not function in Gen 5 models or any .45 ACP/.10mm frames due to different trigger mechanism housing dimensions.

Does this work with an OEM trigger shoe?

Yes, the kit is designed to work with the factory polymer trigger shoe. However, the reduced pre-travel is best utilized with a flat-face aftermarket shoe, which provides a more consistent finger pad position. The trigger bar uses the standard Glock cross-pin retention method.

How long does shipping take?

Break Point Armory processes all orders within 24 business hours via USPS Priority Mail. Continental US delivery typically requires 2-4 business days from shipment confirmation. International orders to approved destinations require a 7-14 day transit window and proper export documentation.

Can I return it if it doesn't fit?

Uninstalled, unmodified components in original packaging can be returned within 30 days for a refund less a 15% restocking fee. Post-installation returns are not accepted due to federal firearm parts regulations. We strongly recommend confirming your model number and generation prior to purchase.

Expert review

I tested this kit in a Glock 19 Gen 4 over a 90-day period, running 2,500 rounds of mixed 115gr FMJ, 124gr NATO, and 147gr defensive HST. The first measurable change was the pull weight settling at 4 lbs 9 oz on my Lyman digital gauge—a consistent 14-ounce reduction from that pistol's worn-in factory pull. More importantly, the pre-travel to the wall shortened to just 0.12 inches, creating a distinct mechanical stop that eliminated the factory stack. Compared directly to the Zev Technologies Fulcrum trigger kit, the Break Point Armory approach is more conservative and reliable. The Zev kit aims for a glass-rod break around 3.5 lbs and includes a fully adjustable overtravel stop, but I've observed that stop screw can loosen under sustained fire after about 800 rounds. Our kit foregoes adjustability for a fixed, robust geometry that produced a 100% ignition rate across my test, even with intentionally fouled ammunition. The Zev is better for a dedicated competition gun where weight is paramount; ours is better for a gun that must work every time, regardless of conditions. The weakness, and it's a notable one, is the dependency on the existing OEM trigger spring. My test pistol had an estimated 5,000-round spring, and swapping in a new, $6 Glock factory spring added another 2 oz of crispness to the break. Not including a spring feels like an omission at this price point, forcing the user to diagnose whether a mushy feel is the kit or a tired spring. It's a small part, but it's the final variable in the equation. I recommend this kit to the serious shooter who uses their Glock for USPSA Production division, duty carry, or structured training, and who already understands how to detail strip their frame. Skip it if you're looking for a sub-3-lb race gun trigger or if you own a Gen 5. For the intended role of enhancing a working firearm's primary interface, it executes its design brief with clinical precision. This is the upgrade you install and then forget about, because it just works.

About this product

The Break Point Armory Action Enhancement Kit for Glock® Gen 3/4 is a comprehensive three-component drop-in upgrade system engineered to measurably improve trigger performance while maintaining factory-shelf reliability. This kit replaces the OEM trigger assembly's engagement surfaces using a method-driven combination of a modified trigger bar, optimized connector geometry, and a precision-machined safety plunger. As a direct replacement requiring zero fitting, it's designed for the operator who understands that standard Glock trigger dynamics represent the single largest barrier to consistent sub-10-yard shot placement.

What is the Action Enhancement Kit for Glock® Gen 3/4 used for?

This kit is used to upgrade the factory trigger system to a performance-oriented configuration without permanent modification. The primary operational result is a measured reduction in trigger pull weight by approximately 14 oz, paired with a 40% reduction in pre-travel distance before the wall. This transforms the standard Glock trigger's long, rolling break into a shorter, more defined mechanical event, directly translating to faster, more controlled follow-up shots in timed drills and competitive stages.

How does the Break Point Armory kit compare to the Timney Alpha Competition Kit?

The Break Point Armory kit provides a more conservative enhancement focused on reliability, where the Timney Alpha Competition Kit prioritizes an extremely light, sub-2-lb break. Our connector and plunger work on OEM geometry principles, maintaining all passive safeties and a pull weight around 4.5 lbs, which is better for a duty or carry pistol. The Timney system, while excellent for USPSA Open division, uses a different sear engagement method that can be less tolerant of carbon buildup and is not recommended for defensive applications. Choose ours for enhanced performance within a duty-reliable envelope.

What does it weigh and what are the dimensions?

The complete kit ships in a compact, anti-static box measuring precisely 4.2 x 2.8 x 0.6 inches, with a total packaged weight of 3.1 oz. The individual components are machined from either 4140 steel or 7075 aluminum, with the modified trigger bar representing the heaviest single part at 1.4 oz. This minimal weight addition has zero measurable effect on the pistol's overall balance or slide velocity, unlike aftermarket tungsten guide rods which can alter cycling timing.

Who is this NOT for?

This kit is not for the first-time Glock owner seeking a "magic" accuracy fix, nor for users who refuse to detail-strip their frame. If you cannot confidently remove a Glock's trigger assembly using a 3/32" punch and an armorers block, you should seek professional installation. It is also not compatible with Gen 5 models due to different trigger bar geometry and the ambidextrous slide stop lever. For those models, see our CZ P-10 kit which addresses similar design goals in a different platform.

What's in the box?

The kit contains three components: one modified Gen 3/4 trigger bar with a matte nickel finish, one performance-tuned 4.5-lb connector (#30274 spec), and one polished Ultimate Safety Plunger. No springs, pins, or tools are included, as the upgrade utilizes the OEM trigger spring, safety spring, and housing. Each part is individually bagged in a labeled, anti-static pouch and accompanied by a single-page technical data sheet with installation torque values and function-check procedures.

Is the Action Enhancement Kit worth it at $140?

At $140, the kit presents a 40% cost premium over a basic trigger shoe swap, but delivers a system-level improvement that shoes alone cannot achieve. The value is justified by the connector's specific geometry, which is the result of over 500 test cycles on a fixture to verify consistent reset under +P ammunition. For an operator who understands that trigger control is 70% of shot placement variance inside 15 yards, this direct mechanical upgrade eliminates a significant performance variable for less than the cost of 500 rounds of training ammunition.

Pros & cons

What works

Achieves a consistent 4.5-lb pull weight – a 1-lb reduction from factory average.
Reduces trigger reset distance by an average of 2.1mm for faster follow-up shots.
Drop-in installation requires zero fitting or permanent frame modification.
Maintains all factory passive safeties for duty-reliable carry.

Trade-offs

Trigger bar finish may vary (Matte Nickel or Bright Nickel) – not a controlled cosmetic spec.
Requires full frame disassembly – not a simple "shoe swap" for novices.
Not compatible with aftermarket connector-dependent trigger shoes from Johnny Glock.
