My wife and I purchased a Ruger SP101 3", for home defense for her I did not like the trigger pull at all, but she could not even pull the trigger,(little lady), so I purchased your Ruger SP101 / GP100 Trigger Spring Kit, and polishing kit., the trigger and the hammer are just right just like the video said, now I fill confident, that she will be safe real nice.
This is the second kit I’ve used
review-star review-star review-star review-star review-star
I just finished up my second trigger job using this mcarbo spring and shim kit. The first was an sp101 357mag snub nose, this second one is a gp100 357mag 6” barrel. I’ve done trigger jobs before with springs from other places. But this spring kit with the shims is the only way to go! I did my sp101 a few years ago, and it’s my edc still today. But I’m a little more impressed with job I did on my gp100, unlike the sp101 it had a decent trigger to start with, but it’s even better now! I also polished the whole gun on the gp100. Here’s before and after pics.

SP-101 trigger job
review-star review-star review-star review-star review-star
Done in 2021. Replaced spring & polished bearing surfaces. Took about 7 hours of work mainly because I was clumsy in disassembling and reassembling. but was eventually successful. Followed the online video instructions which were excellent. Reduced original DA trigger pull to 5.5-6.0 lb. Reduced SA trigger pull to 3.5 lb. Revolver is now much smoother and more accurate. Thanks, guys. Rangers lead the way!

We found with testing and research that Ruger was inconsistent with which spring they used in different models, so we include two different options in our spring kit for you to use the one that fits better in your firearm!

The newer GP100s use a slightly shorter trigger return spring than older GPs. The SP101 uses the longer one.
