You cannot get a permit in my county of California, so in saying that, I am accurate, you could count on one hand, and they are 'connected" . Saying you can carry if you can get the permit, but you cannot get the permit, is the same as not permitting. SO, it is actually not legal but will take forever to get thru the challenges. It went to court, and was deemed unconstitutional, but the state is appealing, so in the meantime, the court is letting the law stand ! For another xx years. Also, what you would have to go thru to get a permit here, the money it would cost, makes it too high of a bar for people of modest means, so there are 2 reasons we cannot get one.
It does vary by county. I was just giving a short version to Gamer in any case, because it is not neccessarily just get a permit, no big deal, in the high population areas.
I wonder how many high population city areas have expensive hoops one would have to go thru, which for people like me would make it impossible, such as paying for the county psychiatrist to vet you; taking 2 or 3 days of paid handgun training; only having the permit apply to one handgun..... I could never afford a permit in my county even if they agreed to let me apply.
On the other hand, I do have a carry permit that is good for most of the country, and the class and test I took for that was reasonable. But, I cannot use it for the 2 states I spend all my time in.
