Review
Got the spring kit on time with great communications from MCarbo team, install was a breeze with the included install pin for the trigger. Went to the range and put about 100 rounds downrange, much more accurate, I combined with a new trigger also which got rid of all the creep and polished all the components inside. Highly recommend the Spring kit and the guys at mCarbo were awesome
Product arrived a day earlier than expected! Unfortunately, I was leaving on a trip and didn’t have a chance to play with the kit. The plastic spring holder was a bit loose and would shift while I was putting things together. I sub’d this rod with a piece slightly thicker. I’m also a model builder! This held much better, yet popped out easily during reassembly. Vids helped, but I did modify techniques by using the mounting pin and a similar sized punch. This kept everything aligned. I didn’t think I could do this work, but it wasn’t hard. A little tricky but it went together and dry tested very well. Now to try it at the range! Very pleased!
I ordered the kit thinking Anything is better than stockk, I can not be more impressed, trigger was tore at 8 pounds and it's it's at 3.8 now, so much better highly recommended
Trigger spring kit arrived ON TIME. Installation was a breeze and my SD9 Functions perfectly. OUTSTANDING kit from MCARBO - HOOYAH! HIGHLY RECOMMEND.
Kit came fast and in perfect condition. Installation video made the job pain-free and takes out the guess work. These guys are passionate about their sport and it shows in their products and customer service.
This is a must do for this gun! The original trigger spring that comes with this gun is terrible! 7lbs+ pull. Installing this kit makes it much better to operate! Brings it down to 4lbs.
Factory trigger came in at 8lbs 1 oz. Purchased the S&W SD40VE spring replacement kit, MCarbo polishing kit. I polished the trigger safety pin, sear, firing pin, guides the slide runs on, linkage that engages the sear... installed springs. Trigger rest spring installation took a few tries but the spring capture pin included was helpful. I use a touch of synthetic grease that came with the polishing kit to hold the capture spring in place. Follow the Installation video closely. Play it back a few times you will get it. Watch the Mcarbo Glock polishing video and do it all at once... i ended up with 4 lbs 1 oz over a 6 pull average. Happy Happy Happy.
this is a great kit. very happy with the results. the video is extremely helpful and customer service is top notch!
A+A+A+ very good product
Great product. Exactly as represented, works great and installs easy.
I received my order 1 day earlier than estimated and everything was perfect. I had a little bit of trouble to install the little spring that goes on the trigger although I was able to succeed after many attempts. They were following up all the time to make sure I got updates about my order and about my satisfaction after getting the product.
The spring kit definitely improved my SD9 VE. Very enjoyable to shoot at the range now. Easy install.
Informative video was excellent and easy to follow. Although the trigger pin on my piston was inserted opposite of video I reversed it and made it work. What a difference on trigger pull. Thanks MCarbo
I installed this spring kit in my new SD9 2.0 and the trigger pull went down to four pounds however I get three out of ten misfires. I'm not sure this kit works in the new 2.0
Over all the just the difference between springs is outstanding m carbon really did a nice job. I was able to install this kit in 35 minutes. Would highly recommend to anyone with a Sd9ve. Can’t wait to get some range time
I was a little skeptical after first installing. Took less than an hour to complete installation, and certainly felt different from stock. Took her to the range today and I could not be happier with the outcome. I’d recommend to everyone lucky enough to come across this great product!
