I bought my first pistol, a Colt 45 Combat Commander, when I was 22 in 1976. I don't recall there being a law against carrying at the time, and this was California. It was pretty much unheard of. I would keep the pistol in my car but I didn't have a holster for it so I never carried it on me. Didn't even think about it at the time.
“A dying culture invariably exhibits personal rudeness. Bad manners. Lack of consideration for others in minor matters. A loss of politeness, of gentle manners, is more significant than is a riot...”― Robert A. Heinlein
