I followed the instructional video. It took me a little longer than the video but i would just rewind. I don’t have a trigger pound test device but it softened my Gen 2 trigger big time!

Great instructional video and great product!

Easy to install they even have a video you can watch on you tube to install part. This spring kit made a huge difference in the trigger pull in my G29 and G40 mos. Hope they come out out with some more spring kits for a couple revolvers I have.

The kit was complete and super easy to install. The videos on here are really easy to follow and he shows the hard steps twice which helps with the install. Once polished and assembled the gun function much smoother and easier. Great product and I would recommend this upgrade to even the novice Glock beginners.

Great Spring Kit - works!! Videos are great

Bought this spring set for my P80 - something had to be done about the trigger pull - this did the trick. Not like you need the videos for installation but they are great info on why certain springs do what and how it affects the trigger pull weight.



Will buy again, depending on if Creepy Joe keeps pissing on the 2A.

Great spring kit great quality

From start to finish. I received the spring kit and polishing kit in a good time for the current shipping situation. Both of the products were in very nice and neat packaging. I used the YouTube video and followed start to finish and it was very helpful. For the price it made a very nice difference by no means is it as good as my zev trigger but it is better than any of the spring kits I have used.

Great Trigger Kit

I installed this in a PSA Dagger which is a Glock 19 Gen3 Clone. Also did the polishing that was suggested in the Video. Your videos are also great and a big help.

Great upgrade

I really like MCARBO’s no nonsense approach to firearm upgrades. No gimmicks or high prices, just ruthless common sense upgrades. The Glock trigger upgrade was a fun and enjoyable project to undertake and I plan on putting one in on every Glock I own. My buddy has a shadow systems and we compared the trigger job to his over priced pistol and most of the guys at the range agreed, the MCARBO trigger job was by far the better of the two. Way easier on the wallet as well! Kudos to the MCARBO team for another outstanding product. Best $15 I’ve ever spent, next to the time I was in Thailand… Do yourself a favor and get this upgrade, you will not be disappointed.

I ordered the Glock spring kit to cut down the 8 lb trigger pull of some of my G 17's. I always turn to M*CARBO first. Their customer service is top notch and shipping was fast. Once installed, the springs dropped the pull down to a manageable 5 lbs. I highly recommend getting a set of M*CARBO springs!

Holy smokes!

My G48 went from 4 3/4 lb trigger to a 3 1/2 lb trigger, besides being much smoother. The BEST money you can spend on improving you Glock.

I’m content for the money spent

I watched the installation videos multiple times before I even purchased the items. I finally bought the spring/trigger sets for 6 of my handguns (3-Glock and 3-S&W). In the Glocks, I noticed the trigger travel/tightness of the trigger more the less or trigger weight. I even went back and tried to go over everything again to make sure I didn’t mess up somewhere, but I just couldn’t really tell the trigger weight being reduced. I’m happy with that along. I then installed a ghost 3.5 connector, and it’s exactly how I wanted it and imagined it would have felt without it. But for 16$, how much can one complain and expect. The knowledge I gain from the videos alone was well worth it for me.

My Glock works like butter. The grinding feel of the trigger is gone. The trigger release is light and really helps with target accuracy. Don’t forget to order the polishing kit. Parts shipped next business day with emails of its progress to my door. The step by step instructional videos will help anyone complete the upgrade with ease.

Impressed- buy this kit

So I’m what you call a Glock fanboy. I have a gen4 23, I had an apex trigger spring kit installed and “buffed” two years ago buy a local dealer that was about $40 more than these kits. In those two years I’ve been taking baby steps in doing this stuff myself. So I bought both gen4 and gen5 kit. 1 for Polymer80 build and 1 for my g45. And let me say, The smoothness of the slide and trigger now is 10x better than compared to the apex. Guys for under $20; don’t hesitate to buy this spring kit. Just take the time to polish everything as he shows you in the video. I have three other Glocks that will be getting this kit.

**note- already got my dad to purchase one for his 43
