Shimming?

I saw another forum user mention that he 'shimmed' his trigger and hammer to take out side play. What exactly is shimming and can an amateur do this with careful instruction OR is it better left to someone that has experience doing it? I do not feel my Blackhawk needs it but I am curious.

The basic concept is to measure your gap and add a shim or shims to center the hammer or trigger. If you check the link above there are instructions and videos on how to do it. Pretty simple process if you feel so inclined and well within the skills of a DIY'er.

This post caused me to check the lateral play in my triggers. I'm seeing about 0.020" to 0.030" amount of play in all of them. Other than that, the trigger is square and there's plenty of interaction among the parts and they work great.

What issues are you having that make you want to do this? What problem are you trying to solve?

I shimmed my SP 101 and my GP 100. In my mind it takes the sloppiness out of the moving parts and creates a smoother operating pistol.

Hammer and trigger shims are mainly intended for DA revolvers, where the two parts may drag on the sides of the frame cutouts when shooting in DA mode. I can't see where shims would really be needed on a SA revolver.
firescout is online now
