    Way worth the money and the time!

    So I bought this and used it on my SP101 last year. I lost a shim I needed and contacted customer service and they sent me a new one. They were very responsive and courteous. Took my SP101 from OK to great! The video is awesome and I couldn't have done without it. Now I bought a second kit for my new GP100 and did the same project. This time it took my GP100 from good to great! The SP101 desperately needed the shims, the GP did not. But no worries, once I had the gun apart I didn't want to determine at that time the need for shims and not have them. I also bought the polish kit at the same time for both. I basically did everything that the video shows. I highly recommend this for either gun as it greatly improved them and now I know so much more about my revolvers! Go for it!


    Very worthwhile

    Wasn't satisfied with another set of springs I'd installed in my SP101 DAO, went looking for something better. Tripped over Chris' video on youtube and was impressed with the material and thoroughness. Ordered in late February figuring on a lengthy wait. Parts showed up in three days and I just got the free time to work it over and install them.

    The MCarbo springs are like night and day over the factory liability law conscious springs, and definitely an improvement over the previous aftermarkets. The secret seems to be that the ends are machined so as to prevent catching and snagging.

    I hadn't previously noticed how gritty the trigger pull was until I watched the video. I'd done some very conservative polishing back in the day with stones, and there was always a risk of altering geometric relationships of the parts. Using Flitz on felt Dremel attachments was an inspired idea; I had some on hand for removing very light superficial rust from various items and it did the job. Chris' explanations of what he did and why to what was very helpful. End result on the action was that it really is like cutting through butter.

    The only negative to the kit that I found was due to my own ocular maturity and ineptitude. The trigger shims are necessarily thin and are like trying to work with aluminum foil. I mangled the included ones to the point where they were no longer usable. Hammer shims, being thicker, were not a problem at all.

    Beyond that, watch the instructional video a few times and pay close attention, particularly when it involves captured springs.

    I plan on buying additional kits for other guns I own. Over time I hope the product line expands. K, L, and N frame Smiths would be a plus, although I understand that the leaf mainspring might be difficult to produce at a reasonable price. And the new lockout parts complicate the overall action. And if Chris is willing to risk hair pulling frustration for a parts kit with a limited market, the Rossi/ Braztech Model 92s cry out for better springs, a metal magazine follower, and a video on what to hit with the Flitz

    Night and day difference between factory assembled and MCARBO Spring Kit with a little love and polishing! Video was great for letting you know where the "oh Sh*t" springs are hiding. I will be buying more spring kits in the future


    Ruger DAO sp101 action job and polish

    M-CARBO rocks!! Followed video instructions and no problems. Action and buffer job was easy. Springs and shims made all the difference. Thankyou for your expertise. Doing the job myself saved me money and I learned just how my revolver operates. Feel more confident and relaxed with my firearms. Everyone should find this company.

    Seeing the video gave me the confidence to move forward and the result was very satisfying. Take your time follow the video and you too will be very pleased with the way your revolver now functions.
