Only my view.......If your going to conceal carry then conceal it. No one should see it or even know that you have it. Do as you have been doing if its working well for you. If you open carry make sure that its visible.Like you I concealed for years until my son turned 21 and wanted to carry, we started looking into the laws of our area and found that we have nothing against open carry. To show support for him I to started open carry. Then I found OCDO and found out that this thing is going on all over(open carry). Now we open carry most everywhere we go I've found out that by OCing that you can help educate other about there right to carry easer than you can by concealing it. this helps to reduce the "man with a gun " call. I also realize thata lot ofpeople who conceal dont care about educating others even tho they talk alot about it. They are also the first ones to complain when the LEO's stop them because of a"man with a gun call" come in.
ComSec is doing a fantastic job at putting together a missouri map of city's that allow open carry. take a look at it.
