Always buy at gun shows or flee markets. Ask neighbors if they have one for sale. Registered guns are confiscated guns. .
Private sales are illegal in California, I do believe.
You do know they do background checks at gun shows too right?
Also, as mentioned by others, private transfers without an FFL involved are illegal in CA.
Flea Market? Seriously? I’d like to hope you are just kidding.
No [legal] private sales in Kalifornistan.
