Again, all of these comments are greatly appreciated!
This is definitely not something I would advertise; it's more of a special situation I'd allow for a specific few customers. It's been suggested by a few repeat customers I frequently do business with(everyone knows I'm heavily into firearms), but I've politely declined thus far. I think I may continue to do so, after further reading. As much as I'd love to trade a few beads for a 1911, I don't think I want to do so within circumstances that could be misinterpreted by the BATF or any other concerned party.
If it were a simple "yeah, no problem", I might, but it sounds like there's a lot more liability and red tape than what it's worth.
Thanks for the input!
