At a recent gun show, I was looking at a very nice blued Model 29-2, 6-1/2" bbl., 95% with only a slight scuff of bluing on end of the barrel. Asking price was $700 obo...so I almost broke my arm getting to my wallet. But then I looked more closely at the cylinder and its drag line. It appeared to me that the cylinder stop was not retracting fully, and it had actually gouged a deep drag line completely around the cylinder, through the bluing and down to bare metal. I told the dealer that the stop was out of adjustment, but he said that all S&W revolvers have drag lines (which is true). However, the drag line on this cylinder was much wider and deeper than I've ever seen, so I passed on the purchase. Is the cylinder stop adjustable? Did I make a mistake passing on this Model 29, even with a deeply gouged cylinder? Thanks.
