Afternoon RhammerWolf shows 2 special spring kits for the SP101 22 LR, trigger, any body know why ? the factory ones are way to stiff.
I don't know why but last time at the range I had many more FTF's in DA!For the post 2011 model you will want the new Wolff spring kit
#17114. It contains a 8# trigger spring and 13#,14# and 15# hammer springs!
I too used the earlier #17113 kit and was never happy with it. Too many FTF's.
I installed the 8# trigger spring and the 13# (lightest) hammer spring.
I don't know if length, wire size or what made the difference, but the new kit Really Works!!
The DA stacks nicely and the SA is much smoother and lighter.
And the best part, after putting about 300 rounds through it I've only had 2 FTF's!
My wife and I both use this gun with bird-shot to kill rattlesnakes around our home and before, my wife couldn't operate it with the heavy springs!
I am aware of the shorter hammer throw in double action.You may already know this, but the hammer does not strike as hard in double action.
When you fire double action, the hammer does not come back quite as far as it does when the revolver is cocked for single action. This difference has a noticeable effect on the strength of the hammer strike. So if you want the revolver to be reliable in double action, you need to fire double action during testing.
I have encountered a number of revolvers that were 100% reliable in single action, but still got occasional misfires in double action. In each case, a stronger mainspring resolved the issue.
