Wolff Springs in a GP100

[jwc]

I purchased a Wolff #17110 Ruger GP-100 RP Revolver Shooter's Pak (9/10/12lb hammer springs (factory spring 14lbs) and 8/10lb trigger springs (factory spring 12lbs) several months ago for my 4" GP100.

I installed the 12lb hammer spring and 10lb trigger spring from the kit and it improved trigger pull in both single and double action. It has never caused a light strike either, even with the Wolf and Winchester primers I use with my reloads.

I found a great deal on a 6" GP100 that I intend to use mainly for single action target shooting. What recommendations do you have for me to optimize single action trigger pull on my new 6” GP100?

I use the same setup in my 4" GPs for reliability (12 lb. main, 10 lb. trigger return). I did experiment a little with one of mine and found the 10 lb. main spring and the 8 lb. return spring yielded excellent results in both double and single action. I did not experience any missfires with Winchester primers. If the sole purpose of the revolver is purely target shooting I would not hesitate to go with this set-up. Just my two cents.

Thank you for your reply.

I thought about doing exactly what you suggested after posting my message since I already have spare springs and swapping them out is not difficult.

It's good to have confirmation this setup works for you. I am eager to see how it works for me after that wonderful 10 day waiting period California requires is over!

There is a whole lot you can do with a GP-100. The basic gun is very sturdy and dependable but there is lots of room for improvement to the internals and the trigger as well as to the exterior. Depending on how far you want to go there are guides to smoothing the internal parts and making modifications. The minimum spring requirement would be to reset the trigger and to pop the hardest primer you are going to use. The grips can make a difference in the shooting as well. If the gun is new or fairly new consider doing a bit of dry-firing to get it loosened-up after a thorough cleaning and lube job. The owners manual and Ruger.com has lots of information and there are even videos there.

Welcome to the Forum. This is my GP-100.

...I'm no expert, Jimbo

To reap the full benefits of polishin & springs ya gotta shim the hammer & trigger !

I use SS a feeler gage to fashion shims , leave .003 clearence & make sure your not to tite & bind .

 

[jwc]

Will you please provide more details on the shimming process?

 

[GP100man]

Yep , ya measure total clearance then divide by 2 less .003"

Then fashion a shim from your "shim stock" , be very careful holding the feeler gage to drill it & use very sharp bits , go slow !!!

Finish your shim by removin burrs & polishin .

The trigger can be shimmed by just sliding the pin out just enuff to insert the shim on 1 side then back thru to get the other in.

Check the trigger close for binding very close if ya use this method !!

Use another gage blade to push the shims in place for the hammer .
