I have had good experiences with Wolf springs. On the other hand, the stock spring lasted 30,000 rounds. I don’t know if a Wolf spring will last longer than that.
That 30,000 is about where mine is. At my age, I doubt I will do another 30,000. I believe the spring in mine is a replacement done by the pistol smith that worked on my 686 when I first got it.I was doing some action pistol matches then and needed it tuned up
Realizing that this is a gunsmith forum and I am not a gunsmith, I have another small problem and maybe some one has an answer to it.
I bought the Wolf spring kit and a new strain screw form Brownells.The strain screw is listed as the mfgr's one. When I put the Wolf main spring in, the new strain screw was about .090 shorter than the one in the gun. It would not even take up the slack in the Wolf spring or the old spring that was in the gun. Using the old longer strain screw, I installed it in the gun with the new Wolf main spring. It was a tad short as I still got light primer strikes. Since the range is 40 miles away, I put new primers in some fired brass and tested with only the primers( no powder or bullets)
Starting with .020 brass shim stock, I placed it between the end of the old strain screw and the Wolf main spring.This worked, and I had no light primer strikes. I then went to .015 shim stock and repeated.That worked.Then I tried .010 shim stock and again I got light primer strikes. I did not have any .012 shim stock and I did not try .010 and add .002 shim stock to it. I will be going to the range this coming week to test it in live fire and tweak the strain screw.
I don't know if the pistol smith made this old strain screw or if there is supplier that one can be purchased from and modified to the correct length.Anyone know of one?
I could use an 8-32 stainless steel set screw if I could find one long enough or modify an 8-32 fillister head stainless steel screw. Or leave it like it is with the .015 shim stock in it. Or buy another factory main spring and use the factory strain screw
