It has been discussed a method to tighten up the action is to put a shim around the hinge pin or in the lug. I am wondering what people do to keep it in place. I have found after a few openings and closings it starts to move out of place. The glues I have tried don't hold.

I was also wondering instead of a shim if anyone has tried steel acra-glass? I'm not sure under the recoil if it would stand up or not.

Nothing is foolproof to a sufficiently talented fool.
