Hey guys, I have a question.
My Walther PPK has a horizontal adjustable rear sight.
I think the sight was moved too much, and now it fits in very loosely. Almost at the point where it won't stay put.
Do you have any suggestions for fixing this?
Ideally I would like to make it harder to move, but not sure what to use. The spacing seems too small for a shim.
Any advice would be greatly appreciated!
