Warning....Long and winded!!! Back story: I've had my eye out for a M1 Carbine for a while. My Winchester 9422 22 mag has served me well for pig hunting but after carrying a friends M1 a few years ago on a trip I knew I wanted one. The light weight and short over all length make it ideal for chasing pigs through the rain forest. I checked out a new gun store last Thursday and low and behold they had a Iver Johnson M1 on the used rack. I know that the Iver's are not USGI, and the later models were known to have problems. This was a low serial number gun with a clean crisp bore. There was no rust, some finish wear on the bolt, and the stock was in decent shape. The action/trigger/ mag release all functioned smoothly. All in all I'd say about 75%, a gun that still looked/functioned well but I wouldn't be afraid to crawl through the bush with. The gun was priced on the higher side, but "want" clouded my judgement and I plunked down the cash and took it home. I cleaned the gun up and on Friday I loaded up and went to the range. Out of the 20 or so rounds of current production ammo (American Eagle, Federal) ran through the gun I ended up with a few stove pipes, some jams, a stuck case and failure to return to battery. The failure to return to full battery was scary because pulling the trigger still let firing pin go, there was a light strike on the primer . I;ve seen some aftermath pics of out of battery fires and it's not something I'd like to experience. I went back to the store after the range trip to talk to the owner. I explained the problems with the gun and I felt that it was unsafe. He let me know that the gun I purchased was on consignment (this wasn't mentioned at time of purchase) and he called the owner and let him know the problems and I wanted a refund. The original owner said he wanted to check the gun out first, which I agreed to and left the gun at the store. This was my first purchase from this store, I understand the risk of buying used but if I'm paying top dollar I expect to get a firearm in safe working condition. I also expect a gun store to stand behind what they sell, you really don't know if a gun functions properly until you fire it. I was hoping to get a call today from the store owner to resolve the issue but that did not happen. I had told the owner that money didn't have to be refunded, I'd take another gun (new) instead. My only saving grace is that I paid with my credit card so I can reverse the charge. I don't want to burn any bridges but I'm not getting stuck with a useless paper weight. So I guess my question is should I wait and try to work it out with the gun store or should I call my bank and dispute the charge? It feels weird asking for advice on the net but out of the 10 or so used guns I've purchased this is the first time I've had a problem. Thanks!!
