So I have some questions.\n\nI am at the range with my friend Bob. \n\nBob is shooting a nice pistol, but shoots mine and likes it even more.\n\nI am shooting Bob's pistol, and Like it better than mine.\n\nCan bob and I trade? Do we need to involve an FFL?\n\nCan I sell Bob my gun? Do I need to involve an FFL for that?\n\nWhat if they are rifles instead of handguns?\n\nIs it State by State? or is it a federal thing?
