I am long retired. In worn work pants and shirt, sawdust on everything, a beard and shaggy hair, a limp from a bad knee, and in my 70's, my wife tells me I still look like a cop. At 6'5" and 250, I will never be Grey Man. But I prefer to not carry my firearm in the open. In the unlikely event I am attacked, I want my .45 to be a terrible surprise.
My chief concerns with open carry is firearm security, and the fact that a visible firearm can provoke escalation of disagreements. Then there is the practical issue of property owners who don't want guns on the premises. In my state the law is, a proprietor can tell you to leave and if you don't, you are trespassing. It can be confusing, but if concealed not an issue.
But if open carry becomes law in my state I will have a chance to strut my bling leather and barbecue guns on my trips to town. I might even wear my cowboy getup.
Y'all do you, I'll do curmudgeon and practice my draw and CQB.
