I wouldn't buy a thing at a gun show because a) the gun check at the door, b) the high prices under normal conditions, c) the amount of non-gun junk sellers, and d) the cost of attending is higher than warranted.
The sellers are out of their everlovin' minds hiking prices through the roof.
The desperate buyers are out of their everlovin' minds for paying those prices.
Don't feed the panic. Buy what you want in local stores or online.
