I’m not the GP, but I’ve sold a few face-to-face.

I find that intuition is far more reliable than documentation anyhow. I’ve turned down several sales because the buyer struck me as irresponsible.

Lots of people will only private sale to someone with a concealed permit as it acts as a form of 'good guy' card.

I never had any evidence of the buyers not being legally able to own them. I simply checked to make sure they were a resident of the state via their driver's license.

Having a higher willingness to pay could be a whole bunch of things; I just found there was a curious number of buyers that would pay over the going rate, which in a free market may have meant there was a reason for it.

I also take ideological issue with the felons cannot own firearms rules. Imo, if you've served your time, your debt to society was served, and your rights should be restored.

I was never under the impression that these weapons would be used for violent crime.
