I have been working on a brand new SP101 w/2.25 Inch Barrel, in 357 Magnum. (New Style Hammer)
Polishing all the right parts
10 Pound Hammer Spring
8 Pound Rebound Spring
Full Shim Package, Hammer, Trigger, and Hammer Dog
I noticed when working on it that the Transfer Bar did not swing freely. You could move it back and forth, but NOT Free Swinging at all. It seemed to loosen up a little as you started moving the Trigger, with the Trigger Assembly out of the Frame.
After having it apart about 5 times, I am about sure the Transfer Bar had something to do with the Hitch.
I noticed when installing the Trigger Assembly back into the Frame that the Transfer Bar Nose would hit on the right side of the Hammer Tunnel and stop upward progress of the assembly, and I would need to push it Left with a small screwdriver to clean it and get the Trigger Assembly to move on into place. (Not Forced, just nudged over)
I finally noticed that the Transfer Bar was moving up the Hammer Tunnel against the front face, and looked to Bump Off the bottom of the Firing Pin at the same time I felt the Hitch.
I polished the nose of the Transfer Bar, along with the Stud, and Sides. This seemed to help the Hitch, but it still is not gone. The Transfer Bar is still not swinging Free either.
Where the Transfer Bar is dragging in the Trigger Assembly is not obvious. I removed the Trigger Shims, and that had no impact on the drag.
The Transfer Bar Stud seems to turn freely in the Hole.
I am a little gun shy removing much material off the Transfer Bar Sides, Trigger Housing, etc. without Divine Guideance from someone who knows more than I do.
I will continue to look things over till I hear back on this post, and see if I have a Bur in the Trigger Housing I may have missed.
I know that the Ruger Trigger Hitch is very common. It also looks like the Transfer Bar Bumping Off the Firing Pin is probably what is causing the hitch to be felt.
What is the process to cure the Trigger Hitch?
