Well, FWIW, here is a true "gunsmithing" story. A man brought in a Ruger MkI* with the long barrel. He had dropped it from a fairly good height and while the gun did not appear to be damaged, the bolt was frozen in place. The boss told him to leave it and we would see what could be done, then came back in the shop and handed me the gun. I asked if the owner had left, and the boss said he had. I picked up the gun, looked at it, slammed the side of the barrel down on the carpeted bench, worked the bolt a couple of times, then shot it to make sure the sights were still good. About a 3 second fix. I don't know what the boss charged the guy, maybe nothing, since the guy was a good customer.

*Contrary to Garry James' quiz in the Feb. G&A, the Mk I was not the Ruger standard model, it was the original target model with adjustable sights. He blew a couple of other answers too, and he made up the quiz.
