I agree with John, that cleaning should be the next step, but it just seems so strange that it happened to both hammers at the same time and then both went back to functioning at the same time. I can't picture how that could happen. What I don't know about the Winchesters could fill volumes, but with two independent lock works it would take a significant sized piece of foreign matter to do that, I would think.

Please let us know what you find. This is interesting.
