I really hate the term gun show loophole

Maybe the situation and laws are different in other parts of the country, but at every gun show I've ever been to all of those people with stands set up selling guns are dealers, so to buy a gun through them you have to go through all the legal hoops as if you were buying from a regular gun store.

I suppose there's a lot of randos wandering around there who own guns who might be convinced to do a private sale, but that doesn't really have anything to do with them being at a gun show except it's a convenient networking opportunity. You could just as easily hang around outside of a shooting range trying to find a private seller.
