Great kit and amazing video
Followed the video to do the full polish, spring, and shim install and it turned out great. Very smooth and lightened up the single snd double action as expected. Between this and my LCP max (spring snd trigger upgrades) I am very pleased.
Best After Market Upgrade
I've used several of these kits to improve the factory trigger pull for both GP 100 and SP 101's . My customers love the improvements, which dramatically improve their accuracy. Highly recommend these kits.
Gp 100 357
This kit made my gp100 feel like the true king of revolvers that it is! install
Was not too hard however i do recommend using a big ziplock bag when pulling trigger plunger springs in and out mine did grow wings but luckily was able to find it .easy to follow step by step and boy what a difference it made . One trip to range so far 150 rounds and no light strikes
ruger sp101 trigger spring kit
what a difference trigger is nice and smooth and easy
Ruger sp101 trigger kit
I really enjoyed installing the trigger kit on my ruger sp101 357 I got the revolver from my sister who inherited it. Apparently someone had a spring kit already installed but I are had flitz and the polishing attachments for my dremel. The video was super helpful and easy to follow. The price is what really got my attention. I am going to do each of my firearm triggers that you have available. Thank you for such a being so detailed in the videos and making such a quality product. I highly recommend your products.

Massive Improvement
Ruger GP100,
Double Action,
Before - double action pull was over what my scale could read.
After - 7 lbs.
Single Action,
Before - 6 lbs.
After - 2.5 lbs. with stoning and polishing.
Better than expected
I knew it would be an improvement, but wow. So happy I did this
Any idea if this kit will work on the Security/Service 6 series? Thanks
Will the SP101 trigger spring kit work on my DA only spur-less hammer Ruger SP101?
Sp101 in .327, awful trigger (horribly manufactured), had gunsmith change to different brand springs, much lighter than the originals I think, now light hammer strikes on some factory and a lot of reloads.
Question 1) Will these springs work on SP101 in .327?
2) Any idea on reloads? Just as a note, my Ruger LCR in .327 has no issue with my reloads….
My 357 sp101 puts a good size dimple in every primer it’s hit with this kit, reloads and factory new.

Hi. Will this will work on the 9mm SP101 also?
Thanks
I have a GP100 in 44special. You are not showing that caliber. Will the .357 spring kit work?

We have not tested our springs with that caliber so we cannot verify that you will see the same results with your model.
I see two trigger return springs in the Ruger GP101/100 trigger spring kit. I've looked in the printable instructions and watched the video but don't see anything about why .

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.
