    Made a major difference in the trigger pull on my PSA Dagger. It's made it easier to stay on target than with the factory springs. I used the 4lb firing pin spring, the lighter firing pin safety spring and the extra power trigger spring. All of them work great, and very happy with the results.

    Love M*CARBO products. A+ service in every area. Even though I live west several states away, M*CARBO orders get to me very fast, which tells me they process orders fast and get them in the mail so customers receive them amazingly fast. Their videos are great too. Every glock needs this M*CARBO spring kit.

    Have installed these springs before in my Glock pistols paired with APEX triggers and a little polishing of all the trigger group hardware. For a final cost of around $150 the end result is a very smooth, reduced trigger pull with a short reset.

    As the saying goes, “this ain’t my first rodeo”. With the video to watch, I decided to do this as if I was a first timer at this stuff. I opened the package and looked over the parts in their individual packages. Then I started to watch the video, stopping when the slide was complete. I took a break, then watched the second half. I now knew how the company wanted this done. I did not do any part of this out of sequence, wanting to see how this project was supposed to go. I started on the slide, stopping the video when I figured it was enough to remember. If I felt I was straying from the suggested way, I’d back up the video and take another look. After I completed the slide, I took another break. Then I did the bottom half the same way. Put the two halves back together, got out my trigger pull gauge and read 3.4 #. Nothing could be easier. A great Glock trigger at a very reasonable price, and not with the cost of a new connector with a fancy name. Take your time, don’t rush, don’t try shortcuts and you will be on your way to being a Glock Mechanic.
