Do a background check for every new passport and passport card.
Mark the passport (card) with guns ok or no guns.
Show your passport (card) to your dealer that is less than 60 days old, have him write down your passport (card) number and name and gun info, pay and carry home your piece.
Make this the way guns must be sold.
It maintains buyer confidentiality. Bars states from accessing dealer lists, but give states the right to request the information by presenting the gun to the dealer or dealer’s successor. Dealer must destroy information within 24 to 36 months of it’s collection.
Democrats’ want universality. We want confidentiality.
My method would create a long waiting period too.
