An Initial Comparison and Review
There are many aftermarket modifications to Glock’s stock trigger, from simple parts (e.g., connectors) to replacement triggers/trigger bar, to drop-in trigger groups, to larger kits also replacing the striker and additional springs. Though Glock has always warned against secondary market parts to ensure the warranty and safety of their products, they have allowed such modifications within an Unlimited division in both indoor and outdoor Glock Sports Shooting Foundation (GSSF) matches. The two factors that previously united all these aftermarket modifications were 1) they were all designed to change the ergonomics and trigger press weight in an effort the improve the trigger with better fit and/or lighter press, and 2) they were manufactured by secondary market companies. Now, with a single email released by Glock during the January 2023 SHOT Show, Glock has changed the second factor by introducing their own Glock Performance Trigger (Currently $99.00).
Currently, there are no plans to ship any Glocks with the Performance Trigger pre-installed and it is offered by Glock as an accessory to be installed in pre-existing 9mm Glocks. The Glock Performance Trigger can fit:
- Glock 17 Gen5
- Glock 19 Gen5
- Glock 19X
- Glock 26 Gen5
- Glock 34 Gen5
- Glock 45
- Glock 47
- MOS versions of those same guns.
Glock is advertising these triggers for those wanting a flat-faced trigger with a lighter trigger press while maintaining the Glock Safe Action System.
Additionally, Glock warns that the triggers should be installed by certified Glock armorers and only in the listed Glocks. ¹
Another factor that unites most previous aftermarket triggers is that they utilize the basic engineering of the stock Glock Trigger simply adjusting trigger bar angles, polishing surfaces, and/or replacing springs. The Glock Performance Trigger utilizes a redesigned trigger, trigger bar, and trigger mechanism. This likely was developed due to Glock wanting to adjust the trigger press and ergonomics of the trigger face
while maintaining the safety standards of a Glock-produced accessory.
It is of note that the trigger bar is not only different in the Glock Performance Trigger, but it also engages in the trigger mechanism housing differently. Specifically, there is a spur on the trigger bar that needs to be seated properly on a spring within the housing for the trigger to operate properly. The trigger comes with a rubber band holding this configuration in place, but if the bar comes loose, the trigger bar will reseat without engaging the spring within the trigger mechanism, resulting in a dead trigger.
An objective test conducted by the author compared an unfired Performance Trigger to an unfired stock trigger from the same Glock 17 Gen5 MOS. Glock reports the stock trigger at 26 newtons or a 5.8-pound trigger press. The trigger press for both triggers were measured and averaged across twenty trigger presses with a Lyman digital scale and then these averages were adjusted to match the factory-listed specs of the stock trigger. The stock trigger press was consistent across measurements and the starting position and reset position of both triggers were near identical. The stock trigger had a trigger press of 5.83 pounds (Standard Deviation (SD) = .21 ounces) while the Performance Trigger had an even more consistent trigger press of 3.56 pounds (SD = .09 ounces). The objective result was that the Glock Performance Trigger had a consistent trigger press of 2.27 pounds lighter than the stock trigger.
The Subjective Experience
Though objectively a lighter trigger press with a flatter trigger face, the proof is in the experience. The subjective experience supports the objective data. Overall, if you are used to the standard Glock stock trigger, the newer flat-faced trigger may take a little getting used to; however, this flat-faced trigger has been common in non-Glock aftermarket trigger replacements as well as in other manufacturers’ guns.
The trigger press is subjectively a smoother experience moving from initial trigger movement until hitting the wall, then break (releasing the striker to fire the gun). This break is not only a lighter press but also slightly crisper and more consistent than the standard stock trigger. In this way, the Glock Performance Trigger is similar to other aftermarket triggers.
Following the break, the reset is more similar to a standard stock Glock trigger coming consistently and noticeably, but also further forward compared to many other aftermarket triggers. This does differ from other products available that often have a ‘softer’ and quicker reset. Overall, the trigger experience is cleaner, lighter, and very consistent.
For those competing in Glock-sponsored shooting events (GSSF indoor and outdoor), there has already been a clear ruling from the GSSF that the Performance Trigger is considered a ‘stock’ addition as it is manufactured by Glock. This means a Glock equipped with the Performance Trigger does not change division. If the Glock had been designated as a Stock gun of Stock MOS, the addition of this trigger does not change that designation. It will be interesting over the next year to see how many stock guns at GSSF events start utilizing this trigger as it does provide a lighter and more consistent trigger press.
I will openly admit I am biased against carrying a defensive gun that features any internal modifications. However, as this trigger comes from the original company and carries their continuing warranty and assurance of safety, I could see those wanting a lighter more consistent trigger in their carry gun considering this accessory for it. Additionally, the similar uptake prior to trigger break and continued presence of a trigger safety further support considering this trigger for carry use.
Overall, there was nothing during my dry fire or live fire testing that suggested any areas of concern for safely carrying a Glock featuring a Performance Trigger, outside of the reduced trigger press.
Glock has made an impact with the release of their own “aftermarket” trigger. The cost versus benefit, when compared to other aftermarket trigger options, results in a solid product at a relatively lower price point that also provides an improved shooting experience. The bonus of a better trigger experience without potentially compromising safety and reliable function or voiding the Glock warranty will also appeal to some users. Finally, the fact that the Glock Performance Trigger can be used for competition without impacting the division that the gun shoots in will further appeal to some.
I will close by adding my voice to others that wonder why this trigger is not set to become the standard trigger in stock Glocks; maybe that will be one of the reveals for the Gen6 Glocks.
¹ There are videos posted online showing how a minor modification to the frame area where the trigger mechanism housing is located then allows this trigger to be added to previous generations of the Glock 17, 26, and 34. This modification obviously would not be covered by Glock’s warranty of the product.
