It almost seems redundant but there are many people out there who buy firearms for defense and don’t get a concealed carry permit. This is silly. I don’t care what state you live in, or what the local state laws say: if you are going go carry a weapon for self-defense get a permit. If you do have one and have to use it, there is no problem (assuming you used it correctly, which is another whole article).
But if you do not have a concealed weapons permit, then you have to explain why you were carrying it, explain that you were not violating the law, and generally get hassled by the local gendarmerie’ who absolutely hate finding unlicensed people carrying weapons. Easier to avoid the problem entirely.
