    Glock Trigger Spring Kit
    review-star review-star review-star review-star review-star
    As per the video I disassembled my Glock 48 Gen 5 MOS, polished all the trigger group parts, installed the spring kit and reassembled it all with no problems. The trigger feels much better now. Big improvement over the stock trigger. I used the four pound spring and it's all working fine with no problems. It should be noted that there is a difference with the Glock 48 Gen 5 MOS and the video. 1, the firing pin safety block is different. 2, Slide stop lever is different, 3, Trigger bar and trigger mechanism housing and spring are different than video. However, the correct springs were included in the kit. Just pay attention. Overall the kit is very good and does make a big difference.
    1000 rounds and not a single light strike.
    review-star review-star review-star review-star review-star
    I have installed this kit in my gen 3, 19. My gen 5, 17 and my Gen 5, 34. Also did jobs on my 42 and my 43. As stated above. I have fired a thousand rounds through these guns and not a single light strike. I did polish the parts to a mirror finish. So between the spring kit, the polish and the Supra lube.. These Glocks Rock!!! I can’t wait until I save the 100 bucks so I can try the new trigger..
    Thanks M Carbo for a great product!!!!!

    I also put a kit in my wife’s custom built AR. She loves the trigger I was able to give her without breaking the bank! 3.5 lbs and smooth as ice… 😁

    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.

    Question:
    I bought the kit for my Glock 19 gen 5, but there is no video or written instructions for the trigger spring (disassembly/reassembly/polishing of the lower). Can I expect to see something to remedy any time soon? The slide mod was a piece of cake thanks to the gen 4 video.
