Best trigger upgrade for Ruger sp101 , went from over 12lbs pull to 5 - 5 1/2lbs very happy with the results. The installation video really help the installation go smoothly.
This was a challenge I just followed the video step by step took my time polish each individual part about 20 to 25 minutes or less per part shim trigger shim hammer put together drastic improvement in double action and single action highly recommend this trigger job with these parts. Take your time to me this was very simple. Took picture of what I used highly recommend these polishing tips. Amazon.
I've spent over 2 hours trying to remove my SP101 trigger group with no success. This is typical of my experiences with Ruger revolvers needing multiple returns and finally just dumping them. I am done with Ruger JUNK!!!!! 4 stars for a product that I can't use unless I cut up the trigger group with a saw!!!!
The springs made a big difference and the installation video was very good. Just be forewarned....Ruger leaves things very rough....I had to get real creative to remove the trigger guard plunger, spring and latch....what should have popped out under its own spring pressure needed to be pulled out....the drill bit trick and polishing help out tremendously. MCARBO gets an A+, while Ruger needs to up their quality control.
I hesitated to buy this kit because the hammer spring seemed too light but I'm really glad I went for it. I'm very handy but I'm not a gunsmith and I had all of the trigger work done in a couple hours of not working very hard at all. I initially liked how the trigger felt and went to test it at the range the next day. It fired every type of magnum and .38 I could get my hands on 100%. It feels almost as good as my Smith and Wesson performance center revolver, which is excellent considering I'm not expecting any job offers from performance center. Don't hesitate to buy this for your Ruger, the difference is night and day without losing any reliability!
I didn’t achieve the sub-5 lbs but I reduced the double-action pull on my GP100 by 2 lbs to 9 lbs 13 oz. I’m not terribly disappointed with that as it is a very smooth 9 lbs. A nice improvement. Well worth it.
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
I recently bought my SP101 .357 snub nose and wanted to clean it after first time at the range. Good time to improve the trigger pull. Video guided me through a job that could have been confusing. Quality of products and packaging first rate. Very happy with the entire experience.
Bought a lighter spring for my ruger Gp100, was very intimidating process until I saw your video. I bought your spring kit and went by the video, it was meticulous, a great job was done, thanks
I started with a SP101 with 12+ lbs trigger pull, bought the kit, moto tool, and Lyman digital trigger pull meter, followed the hour and a half video, and when I was done it felt smoother but the double action still read at 10 to 11 lbs. A huge waste of time and money. If mcarbo can do it better then save the expense of buying a trigger pull meter and moto tool. And send it to them mabey they can do a better job, but I used their kit, and followed their video and am VERY disappointed.
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!
I used this kit on an sp101 in 327. Trigger from factory was terrible and lots of slop in hammer and some in the trigger. Installation video was fantastic, did the buff and fluff of internals and installed the kit. Trigger was immensely improved and slop in action reduced. I feel that they went just a little to light on the springs. Trigger return is ok if a little spongy. Upon doing function check with live ammo, I had about five light primer strikes with standard primers out of about 150 rounds. I haven't checked with magnum primers but believe that I would have more due to increased hardness of the cups. I feel that an increase of between 1-2 pounds on the springs would make this perfect for carry without losing reliability.
Great video tutorial and well thought out package contents. I was actually fixing an ‘experts’ work and this kit restored my GP100’s reliability. The shims, polishing and spring combo all combine to make a smooth and solid revolver. Overall took me about 4 hours as I took my time and made sure I had everything correct.
I followed along via YouTube and made great improvements in my revolver.
Seldom do you get more than what you expect out of a product,....but this is one of those times for me. This kit was easy to install and while I had it apart I polished all wear surfaces. Improved both DA and SA tremendously on my SP101. The video that goes along with this is great.....to the point and not too much talking. Very informative and easy to do....thanks Mcarbo guys.
Cheap and very nice upgrade. Lost a star because I do not think most folks will see the 50% reduction advertised. My double action went from just a smidge over 10# to about 7.5#.
