not a gun but I traded a motorcycle years ago to a guy with a car I wanted. He then traded or sold it to a guy in KY without registering it. I had a detective in KY call me because some dude ran from the cops and wrecked out. Last person it was registered to was me of course. Nothing else came from that, they were just trying to get info, if it was stolen ect.. Since Ga doesn't requite a BOS to register I didn't even have that but I told that to the detective and I had cancelled insurance and registration the day after I made the trade.
