Hi Folks, I went to buy a 9mm Walther PPS from a sporting goods store. I asked to see the 9mm PPS behind the glass to help make my decision. It so happened that the display gun had a scratch on it and I asked if they had any more. The saleman brought out two others and let me choose between them. I bought one of them. I went to the range today, a week after the purchase, and I noticed it was a 40. Basically, in my exciement at the gun store I did not think to check to make sure it was the right caliber. I even bought a couple of boxes of 9mm ammo along with it. I have no desire to own a 40. My other handgun is a 9mm and I wanted another of the same size for convenience. I spoke with the manager of the store and he said the best he can do is have me bring it in and they would look at it and it sounds like they may swap it or at worst buy it back used. Has this happened to anyone before? Obviously, I think they should do an exchange. The manager would not commit to it. I understand that I have responsinilty, but they are the one's that screwed up. I dont know a thing about selling guns used, how much would I lose if that is all they will do? It cost 650 new. If they wont do the exchange can I just leave the gun on the counter, walk out, and dispute the charge on my credit card? Curious what you folks would advise I do? Any help would be greatly appreciated. Keeping the 40 is not an option, so such a suggestion will fall on deaf ears.
