Just for fun, I'm going to do what you suggest. I'll hand carry a copy of the federal statute and the background check form to the dealer I faxed info to recently, along with my photo identification, property tax statement, utility bills, auto license plate registration and checking account statement. I'll also take all the receipts from his store for guns I've bought in the past.
This has evolved into an experiment instead of a gun buying journey. I'll report back on my findings. We probably can predict the outcome, can't we?
Pretty sure we know what the outcome will be, but I am very interested in what you find. Just the other day, and more then a few times a year the LGS encounters similar situations with people interested in buying a handgun. One of two things TYPICALLY come of such encounters. #1 the LGS owner lets the person inspect whatever guns he/she is interested in buying, and if a purchase is desired, he will offer to ship it to a LGS in the customers home state to do a transfer in the way most of us are familiar with interstate sales of handguns. #2 he gets a funny feeling about the whole deal, and basically blows the customer off without trying to be rude.
If there is a legal and viable 3rd option, I think I know a few guns store owners that may be genuinely interested in the circumstances that need to be met for this type of sale.
