I had an annoying thing happen at a recent gun show. I purchased a revolver advertised as "new" and only superficially inspected it before taking it home. In accordance with the rules of the event, the cylinder was zip-tied. When I got it home and removed the zip-tie, I immediately noticed that the cylinder spun freely, no lockup at all. Further, the hammer did not feel right when cocked. When I inspected the cylinder I developed doubts that the gun had not been fired. It being a 2 day show, I took it back the next morning to the dealer at their table. Together, we went to a gunsmith who took it apart and found missing parts and signs of prior disassembly. The dealer wanted to fix it for me, but in my view I had bargained and paid for a new gun, not a repair project and I asked to reverse the transaction, which eventually they consented to. The dealer made a big deal about how they were doing me a huge favor and that nobody else ever would do this, but only were doing it because they mistakenly advertised a consignment as new. I'm pretty new to the show scene... this kind of thing must come up. I've bought new firearms sight unseen before (gunbroker, etc.) and never had such a problem and would like to avoid it in the future. Any thoughts on how the situation was handled or other advice?
