One of the first, and many things I check on a used S&W revolver, is the ejector rod. I shy away from bent ejector rods. Always valuing advice from folks more knowledgeable, Why would, and how could anyone bend an ejector rod? I always lay the revolver on the edge of the display case, open the cylinder, and spin it to check for run out. Always hold it up to ceiling lights, and cock each cylinder, and if I see uneven light between cylinder and forcing cone, I get uneasy. Had a lot of looks from doing this.
