PA used to have a program called "SPORT", meaning Sportsmen Policing Our Ranks Together. The premise of it was, that we gun owners, are more in control of public perception of firearms than anyone. Just because we can, does not mean we should. Think for a moment about the protests going on in this country and the public perception of those dressed in black, carrying firearms (some protesting, some not).
About a decade ago, I was at an outlet mall in SW PA, and this guy was walking around, with a longish coat on. On his belt, was a holstered revolver. The guy made a point of using one of his hands to keep the coat pulled back, so all could see the pistol. Legal? Probably. Smart? Don't know his motives. Did he impress others? Probably, but not in the manner he desired.
