Is it safe to buy firearm from pawn shop?
no Only if the pawn shop has a good reputation and you trust the owner. And if you know what to look for in a used gun.
When a person sells a firearm they essentially sign a contract stating that the firearm is in fact said person's property. The pawn shop cannot treat everyone as criminals and it rarely happens, but it does from time to time. The original owner must file a police report when firearm was stolen. There is some paper work and steps but it will be returned.
