I would try to work with the dealer to by the two guns you want. If you go around him and buy them directly you know that in the end he will find out. It is not like you can just show up with the guns in question and have him not add one and one to get two. Then your dealer will never again show you respect and trust that you have built up. He may refuse to deal with you ever again and most likely tell others what caused you falling out. Perhaps you can get him to hold the guns on a lay away or time payment agreement. Or maybe he can sell something for you to make it happen. Burn a bridge and you can never go back.
