    After doing a trigger spring job and polish on my Glock 44 I immediately ordered the kit for my Gen4 19. four days later I had it in hand. Well it was another successful job and smooth, smooth, smooth. I had to double check a couple of installs on the video but all in all I really didn't have to watch it through and through. I did as well polish the locking block as I did on my 44.. With these two completed now I am looking at polishing my AR's and six shooters.. Thank you guys and God Bless the United States of America

    Everything was delivered on time and fast. I ordered both the Spring Kit and Polishing set up. I had watched the video all the way through prior to ordering and then while doing the actual R&R. There were a few differences with Glock's 44 the most frustrating was R&R of the power trigger spring assembly. All in all it was a piece of cake and polishing was very "Zen" like. Ordering another kit for my 19 today, Thank you Guys

    Big upgrade. Small cost

    Dropped the 4lb spring kit into my Glock 23 and polished everything. Am averaging 4.83 lbs down from 6.7lbs stock. Also, the videos for the install and polishing are great. Highly reccomend this for any glock owner.

    I recently used a spring kit from M-carbo for an LCP and was very pleased with the outcome. I was not happy with a Glock clone build as the trigger pull was horrible, so I installed the M-carbo spring kit as well as polishing the suggested areas of the trigger linkage. It was like a totally different firearm when I was done. Thank you M-carbo. I will be buying from you again.

    After following the detailed video and even with my little experience, I still created a lighter and smoother trigger than the factory one which came in my Generation 1, 17 (look at the pictures below of the average trigger pull).
