Just goes to show your lack of imagination, jOe. The brass shim was used in the Nitro Special, that was written about in DGJ, for decades, with regular use with hot loads. The new owner knew about it when he bought the gun and continued right along. Normal typing paper, with a coating of oil, doesn't compress, at least not much. As long as you know it is there, and don't take the gun apart, it can't really go anywhere.
A good repair can be done in the future, after our hero has discoved other facts about the gun, like, for instance, if he can hit anything with it, or, if it needs other big dollar repairs. In the meantime, he can use it with a shim to discover other warts, or. lack thereof. At least it doesn't look like he will be sleeving it, eh jOe?
Best,
Ted Teddy seems yOu like to try and trip my trigger but you have a problem taking it like a man...least I've owned some guns that were worth "sleeving"....darne it. I got to give to you..you really added a lot to this thread...telling a guy to shim his gun with s piece of typing paper....lol

Shimming is a legit fix. The objective of "on-face" is to have the barrels tight against the breech face when the gun is closed and locked. A few thousandths inch gap between the hook and the pit will cause "off-face." Filling those few thousandth with a shim will solve the problem. First, the shim must be mostly imcompressible, like metal or oiled paper. Second, the shim must have some resistance to wear, like kept clean and lubed. The longivity of the shim depends on the quality of lube maintenance, material used, tightness/correctness of original fit, and the pressure of loads used. An attached shim is more convenient at cleaning time, but an unattached shim is easily put back in place after cleaning.
Shimming a bearing, which the hook and pin are, is not news in the world of mechanics; people have been doing it for many years in more demanding applications than on sporting guns.

I think Tom Joad did his over a ditch in the rain in Grapes of Wrath--rod bearings of course but as Don says, same principle--taking up the slack.
