FYI,

I gave my GP-100 a trigger job about a week ago. I polished everything up, and followed the IBOK. (Thanks for that great resource.)

Yesterday I updated the springs as well (they were stock). The lighter Wolf trigger return spring was very helpful, everything there worked fine. I ended up going with the 8# with no issues.

Where I had a problem was with the Wolf hammer spring. Both the 12# and the 10# were longer than my stock spring (supposedly 14#) by about 1/4-3/8" . These Wolf hammer springs would them compress and drag on the hammer bar that pushes the hammer. This dragging was causing a MUCH rougher trigger pull. The start of the pull was all hesitant and then it seemed to stack up as I pulled through the full DA. It was not nice at all, and, honestly, the pull weight different was truly marginal to feel (I did not measure).

I wonder if the Wilson Combat hammer spring is like this too, as I truly have to recommend against the Wolf hammer spring as a step *backwards* vs. the stock hammer spring. The Wolf trigger return spring was fine, and the trigger, hammer, and hammer dog shims I got from TriggerShims.com are great as well.

Your mileage may vary, but this was definitely the case on my GP-100 with my Wolf springs.

i didn't have that problem with the Wilson springs that i got on friday. also do you have the strut and bottom retainer in the correct position?
did you de-burr the hammer strut?

I got my GP100 down under 7#'s and it's smooth. I'm using the lightest Wilson springs.

I had everything in the right place... The Wolf springs were just longer than the Ruger spring in their uncompressed state. Yes, the hammer strut is shiny. The trigger feels great with the Ruger spring.

Maybe i should have gotten the Wilson springs...

I have to agree with Quack, it sounds like you had something in backwards. When I did the Wilson Combat kit I had the bottom retainer plate in backwards and produced what you described.

Did you just polish the ends of the strut, or the whole strut?

quack

polishing the hammer strut will make it shiny, but can leave the rough edges in place. I used stones to remove all edges/burrs before polishing.

It really appears something is not placed correctly.
It should fit fine.
Check it over again.....re-install.....
Hard to evaluate it without it on my bench, but it
appears something is being overlooked.

Agreed, I go a lot further than most myself. I make sure all four edges are smoothed to the point of being rounded. It is amazing how much drag and friction can be caused by a binding spring.

I may try it again, but I am pretty certain I had it in there right. I took a photo with my phone before I took it apart, and everything matched.

I did indeed stone the edges of the hammer before polishing.

I don't know about the Wilson springs, but the Wolf springs I got are distinctly longer than the stock spring when uncompressed. Both the 12# and the 10#... And both felt rough, especially at the start of the pull.

quack

besides the length of the spring, there is also the diameter of the wire used to make the spring, so it may be longer, but the wire may be smaller. also count the number of coils of each spring as the longer spring might have fewer coils.

When you received your wolf springs, did they come in one complete package or were they in seperate packages? Was the package marked or were the packaeges marked? Was the package or were the packages sealed from the factory? Could be the person pulling things in the warehouse grabbed the wrong springs?

quack

just looked for you and this is a 10# Wilson spring that i just took out of the package vs the factory spring.

Wilson on the Left, factory on the right.

ThreeFiveSeven

Quack, yes, I believe they may be the correct force, but due to their length they stack up and bend back and forth over the hammer strut moreso than the stock spring.

Anyone with the Wilson kit able to compare one of theirs with the stock spring? Are the Wilson springs longer?

Also, my GP100 was made in April of 2012. I have read someplace that Ruger was using better springs in the recent years. In other words, these Wolf springs may have been an improvement over an older stock spring??


I double checked the packaging. They came in a kit. Each spring was in its own marked bag. I tried both the 12# and the 10#, and, presumeably due to the binding, they both felt about as heavy as the stock spring, and both were rough.

quack

and with the hammer down your hammer strut should look like this. If you have retainer on backwards, the strut will be towards the front strap and not parallel to the back strap.

ThreeFiveSeven

That picture of the lengths is similar to the Wolf springs...

So you find your longer springs smooth?

Maybe I had something in wrong, but I did it with two Wolf springs, which both felt bad. Then I went back to stock with the same method and all felt buttery smooth.

I may try once more in the next day or two. I will recheck the hammer strut for smoothness (burrs) as well. It was really weird, the roughness was primarily right at the beginning of the DA pull.
