This is a quality kit with everything you need to do the job. The installation video was superb and easy to follow. ended up with a little over 3 lbs. single action and a little less than 10 lbs. trigger pull double action. I did the deburring and polishing of the various parts and it is soooo smooth. I would suggest deburring the crane passageway because it had numerous burrs also.
Great setup! Couldn't have done this without the video. Unfortunately I lost the pawl spring lol and had to get a new one. Lol works perfectly now so smooth. Made my favorite gun even sweeter thank you!!
This is my second kit and they work great. Made the trigger pull double and single action so much better.
Easy install after watching video, amazing difference in trigger pull, wish I had access to trigger pull gauge. Only drawback on my part, I didn’t see the polish kit and ran all over town to build my own. Highly recommend, turned an ok gun into a great gun
The SP-101 TRIGGER SPRING KIT arrived on time as promised. I watched their 90 min video on the SP-101 trigger job and learned a few things even though this is my third SP-101 trigger job. Installed their new trigger and hammer springs along with their hammer and trigger shims. New trigger & hammer pull is now less than 1/2 of what it was before trigger job. The springs and shims seemed of very high quality & I would purchase again. Their SP-101 trigger job video is the best I've seen & you should invest 90 min to watch it also if you intend to do an SP-101 trigger job in the future. RME
Put this kit in my Ruger SP-101 to reduce the trigger pull. The parts arrived quickly during the Xmas rush. Everything was of high quality, the parts fit, and the MCARBO instuction video made it all make sense.
I used this video to fine tune my GP-100 with some wolf springs. Then I ordered the MCARBO kit for my SP-101. Turned out slicker than snot as we used to say. Best video that I have seen on fine tuning a Ruger. Thanks gentlemen! Hooah!
I am a novice gunsmith. Used this kit on my personal handgun. polished all parts as done in your video and installed shims. definitely smoothed the action and reduced double action pull weight. However I have encountered a few light primer strikes after the upgrade. Will continue to test with various ammo but at this time can not recommend for a self defense weapon.
Put one kit in a SP101. Used both springs, the hammer shims, and did the drill trick from the video. No other polishing. DA 5lb 11oz, SA 2lb 3oz. Put another kit in a GP100. Used both springs without any shims or polishing. DA 5ib 6oz, SA 2ib 6oz. Was a little worried because the trigger spring was slightly longer than the stock spring. With the consistency between these I plan to order a third kit for another SP101.
I just received the SP101/GP100 Spring/Shim kit. My plans are to perform a trigger job on my new GP100 3" .44 SPL. The kit arrived well packaged, in a timely manner. For small items like like this, 1st Class USPS is the best method to ship. Shipping costs were reasonable and because I live in FLA, State Tax was also charged. The package comes with a reduced rate Trigger and Hammer spring, a small container of PTFE Grease and two (2) color-coded containers for the Hammer Shins (red) and the Trigger Shims (blue). A nice touch. I like that the 'kit' comes complete with everything you need to perform the upgrade. This is my first purchase from M*CARBO, it won't be the last. In fact, I just ordered the Conical Polishing Fobs and the Flintz Ramp polishing kit. I've watched the Trigger Job video several times and believe the task is well within my ability. While I'm not a Gunsmith, I've been working on firearms for the past 45-years and feel very confident, especially with Mr. Nelson's video for quick reference. My initial contact (email) with M*CARBO was to comment on the video. Mr. Nelson was kind enough to respond. In my opinion, he's a good guy. Being a Veteran myself, I like to support Veteran owned businesses. b/r TINCAN_SAILOR
received my order in just a few days. Everything came in the kit that I needed. The install was easy, and the end results were great. I was impressed with the outcome. Great place to shop guys!
Thanks for a great video of the installation have never done anything like this and was able to complete the installation with only minor problems. It's like I have a different pistol, feels great. The minor problem was when I installed the trigger assembly, the latch pin would not come out far enough to allow me to pull the trigger all the back or install the hammer. A few hits with my plastic hammer allow the pin to move back.. Don't know if it was the cause of the weaker trigger spring or just my GP100. Thanks again for a great product and video...
Using all of the parts included definitely improves the smoothness of the trigger pull motion, and does reduce the pull tension. Understand though, this process does not give you a hair trigger effect.
Took my time installing the spring kit for my Ruger SP101 357. Watch Chris video while installing - very helpful, rewound video when needed and polished parts turn out GREAT. Best money spent on firearms in years. Thanks for a great product. Vollmer
The installation of the trigger spring set, and the polishing of interfacing parts seemed like a daunting and difficult process. The tutorial video and the cautions and hints presented along the way made this possible for me. I had never even touched a firearm until I was 65 years old. Since that time, I have fallen in love with shooting and have purchased and used a variety of handguns and participated in a couple of womens’ shooting organizations. I completed this complete trigger job using the polishing tips, shims, springs, and polishing compound provided with my order. The job did take me about 5 hours, but this was due to my inexperience and need to stop and rewind to watch some tricky parts multiple times. I am so pleased and proud to have accomplished this project successfully, and the gun action is so smooth. You know the parts and instructions are great if a grandma going on 70 years of age can feel confidence to undertake the project and successfully complete all the steps (and not loose any tiny flying springs). I also completed the spring update on my Sig P238, thanks to MCarbo parts and video tutorial. I learned a lot and am pleased with the results I obtained!
Thanks to M*CARBO I received my order promptly! The springs only kit made a noticeable difference in trigger pull, which I am pleased with. I am now convinced that the complete trigger kit will produce a more perfect experience while shooting. A smooth trigger pull means everything to accurate shooting! I am treating all my stiff guns now! I only replaced the springs, and wow what a difference. I did not do any of the polishing as shown in the video, I’m happy with what Inhave now!
