rebAl, not sure about pawn shops, but, I can tell you that if you bought it at an auction, it's yours no matter what. If you buy a gun at a gun show, depending if it's licenced dealer or a private sale. Most of the time, if it's from a dealer, you can get trade in value for another gun. Depends on the dealer. If it's from a private individual set up at a show, your probably on your own. gypsyman
