If you don't detect a loose lug or loose ribs and the forend is not falling off when you shoot, attribute any strange sound to what is normal in a factory fitted gun. Kiss the ground if you have a good 21 for a good price. Gunflint, thanks for the support. I'm not much of a diplomat, just want everyone to have a good time. Klunkermeister can't have been serious. I can't buy back any 21 I've sold in the last ten years for any price. I've tried and failed. By the way, I went to an LCSCA shoot not too long ago where they mostly all failed. What would Klunk have thought about that? I still like Smith guns.
