What Does Adding Shims Do to a Revolver

[writwing]

Read the post about the GP that had shims added. What is the reason for adding shims? Who makes them?

Thanks

Put simply: Smooths things up. Did nothing but put a trigger shims.com kit in my SRH .480 and the Single Action trigger pull went from a raspy inconsistent 6.5-8# to a clean 4.5# which is where I like it for hunting (cold hands etc.)

What they basically do is center a hammer or trigger in the frame, eliminate side to side movement, remove the part from friction contact with either side of the frame, and with that reduced friction comes a smoother travel.

Good question for the folks in the "Rugersmithing" section. Ya got some wobble in your cylinder (endshake)? Maybe a bit of excessive spitting sideways? Shims are the best place to start.
Jerry Kuhnhausen's books spell out the process very well.

The trigger on my SP101 was excessively heavy and crunchy as it came from the factory last year. I installed shims on the hammer and trigger first and that yielded some improvement - smoother, but still too heavy. Lighter springs helped deliver the trigger pull I have now, which is smooth, but still safe. SA pull is awesome.

With properly installed shims, your hammer and trigger won't feel wobbly.

Something else nobody has mentioned, and this is my personal opinion, a properly shimmed sixgun will probably last longer and be far less likely to get loose because the hammer and trigger aren't being subject to lateral movement or any sort of twisting in use.

I think the shim kit is well worth the money. Also Lance is a first rate guy to deal with. I once ordered the wrong size and had to send the package back and he put the new package in the mail to me before I could get to the post office to send the return package back to him.
