Re: side arm carrying before 21?
I am 22 and I can say when I was 18 I didn't need a gun at my side. I would have done something dumb. Now that I am older and have been out in the real world a few years (plus I'm married) I understand the responsibility much more than I did before.
That being said as stated before here you can carry openly if you are 18. But I would recommend against it as it'll be a hassle with LEO's while they try to sort things out. plus as you said many people are bigger than you and could take it away if they catch you by surprise (please no OC arguments here).
Also most young guys would want a gun on their side to show they are tough, very few want it for self defense. Something to think about
