Glock Gen 1-4 trigger kit.

Pros:
Cons:
Followed the video to a T. Was super easy to clean, polish and apply new springs to Gen4 Glock 20 and 29. The trigger is crisper and resets better. I felt an improvement right away. Shot a few rounds and there's an improvement. For $15 its too easy of a decision. It's not a sig or walther trigger but its an improvement..

Glock Trigger Spring Kit Review

Rating:
Pros:
Cons:
Outstanding product. I have a Glock 34 Gen 5. I added a M-CARBO spring kit along with a Zev Pro Trigger and was able to consistently obtain a 2.14 pound trigger pull. Note this was after polishing the trigger based on the M-CARBO video. With the Zev Trigger alone I was only able to achieve a 4 pound trigger pull. The trigger now is smooth as butter. I will be buying additional components from M-Carbo. This is the best $15 investment I ever made to any of my firearms.

Very smooth trigger

Rating:
Pros:
Cons:
I installed the #4 firing pin spring. Polished the firing pin and firing pin safety. Replaced the firing pin safety spring. Excellent results, trigger is way smoother with what appears to be lighter pull. Don't know cause I do not have a trigger gauge. Will order the same kit for my Glock 17. Be careful with the extractor plunger spring. It can go flying on you (or at least mine did). Lucky for me it landed on the back of my neck. Definitely worth the money and it may appear difficult but it is not that hard to do.
