Welcome to Ok and okshooters. You can’t sell a handgun to a resident of another state. ATF are at the show and could be posing as regular folks. It pays to be cautious.I'm new to the state, would you mind sharing that law with me. I'm from Arizona and there, we weren't mandated to enforce ATF laws. Our didn't require us to check ID or anything for private sales.
Not trying to be a dick, I just don't like the idea of trying to card another american, I'm not the ATF and I don't want to do their crappy job.
