I'm not sure this has come up before on this forum but I thought I would ask for opinions on this matter. I don't wish stir up any ill feelings, make accusations or put blame on anyone. I'm just looking for advice. Well here is the skinny and I guess its more of a moral question... So I listed a revolver for sale or trade. It was an older revolver. It was in working order and finish was decent. I had owned it for about 10 months and shot it maybe 2-300 rounds through it. At one point the mainspring did break and I replaced it with an aftermarket wolf mainspring which I fully disclosed in my classifieds ad. I gave all the details I knew about it and its condition, providing pictures at many angles and answering anyone's questions to the best of my knowledge. Firing the gun before and after the spring replacement showed no signs of timing or indexing problems that I have the knowledge to diagnose. It functioned fine for me but was just not my favorite and I wanted a 357 instead so I put it up on the forum to see if there was any market for it. I had a someone offer to do a trade for my gun if I threw in some ammunition on my end. We sent each other some messages back and forth discussing the details and answering each others questions and everything looked good. Well I accepted his offer we both drove an hour each way to meet each other in the middle, met and inspected each others guns, shook hands and made the trade. I was happy and I assumed he was as well as we both were being honest and getting what we wanted. Well I get a call from the guy now and he said he took it out and shot the gun and it was giving him problems. He said it was not indexing properly and skipping chambers when he fired it. Problems that I had never experienced with it nor have the knowledge to know what would cause them or what he had done to it. I try to be an honest person and make fair deals and I wish every one to be happy on both sides. I think my trade ratings on the forum reflect that. I'm trying not burn anyone but now he wants to do trade backs. I understand his side of it as well if it did indeed start acting up the first time shooting it then there would be some concerns. I'm not too thrilled at the idea of getting back a broken gun when it was working when it left my hands. I think we were both aware that it is an older gun and not to be expected to be perfect but it functioned fine for me and I answered his questions about it honestly beforehand so he knew exactly what he was getting. I guess my questions are should I just buck up and take it back and try to fix it myself to avoid any bad karma? Try to find a fix for him so he can get it working? Or tell him a deals a deal and sorry I can't help ya? If it were your shoes, what would you do? Also what are some of your ideas as to what might cause a revolver to skip chambers?
