Geo, you bring up an interesting point/question.
If your out of state son came to Georgia and you transferred a gun to him legally through an FFL Licensed Dealer, he could then legally take his gun back home to the other state, correct?
So does the same thing apply to Kalifornia residents?
One of my sons lives in Montana. Sometimes when he visits, I give him a gun. We book the transfer through my local FFL since an FFL can transfer a long gun (shotgun or rifle) to a non-resident.
However that only works if the transferee's State law is not violated. Montana is pretty gun friendly, so there's no problem in my situation. If he lived in California, State law which is more restrictive about transfers than the federal gun control act would prevent a legal transfer.
There must be some way California residents visit an out of state gun show and buy guns. Maybe there is a way under California law to
"validate" the out of state purchase when you get back home? I don't know...Geo
