Trigger/Hammer Shims?

I've been reading a little about people "shimming" the trigger and/or hammer on their revolvers - particularly the Ruger SP101. Unfortunately, haven't found much that actually explains what shimming is - why you'd do it, how, etc.

Can anyone shed some light on this? Thanks in advance!

They are super thin "washers" that fit over the trigger and/or hammer studs that reduce the amount of "wobble" as the parts cycle..

Now I see light scratch marks on the sides of my trigger and hammer - would these help solve that? Easy for a DIY install?

Back to the Rugerforum, seek out Flatgate or Iowegan...

Note that these may require some fitting by lapping the washers to get a snug fit.
You typically use one washer on each side.

When installing them, use some good grease as a lubricant to prevent galling.

Another source for trigger/hammer shims

I recently installed trigger and hammer shims on my Security Six and my Redhawk. The shims seemed to tighten and smooth the guns action. It finally has the feel of a precisely fitted handgun. No more rubbing of hammer on the frame or trigger on the trigger guard. After installation I removed the hammer and trigger and polished their sides for the last time. No more scratches from rubbing. If you have already spent time polishing the action this is the next step for additional improvement.

I got the shims from Lance Shively. Great products, prices, and excellent service.

PS I checked out the brownells links listed above and the fine print indicated that the Power Custom shims were for Ruger single action guns. I dont know if the Power Custom shims would fit the SP101. The shims I got from Lance fit Secirity Six, Redhawk, GP100, etc. The following are the measurements from my gun and the shims I ordered:

Hammer pin dia: 0.186” Hammer end play: 0.010”, use 2 0.005” shims

Trigger pin dia: 0.093” Trigger end play: 0.006”, use 2 0.003” shims.
