You're right. There will be the 5% who will guess that I'm probably carrying. They won't know for sure unless I'm forced to pull it. And of those folks that do guess that way, I'd say that 95% will be either LEOs or other people who carry concealed. In the end, I'd say there was very little chance that a nefarious type person will "make" me as being armed.
OK you just keep believing that
