Stopped at WalMart tonight looking for a Henry Yellow Boy .38/.357. Of all things they had one behind the counter. I asked to see it and the clerk said he needed my drivers license before I handled it. I asked why and he said incase I run out the store with it. I was not satisfied with that reply so asked to speak to a manager. An assistant manager was called on their phone. The assistant said it wasn't because I would run out the store with it but because its a federal law. I asked him to show me and he told me to look it up. So, does anyone know if this is true? And if so. where can I read it myself? Thanks for the help.
