I think that generally speaking only police officers and bad guys are observant enough to spot most modes of concealed carry. I've carried a holstered J-frame or the equivalent in my right front pocket for around nineteen years. Nobody, not even a cop, has ever said a word.

People have other things on their minds, and on their phones, nearly all the time. But there are plenty of little handguns with enough punch to save one's bacon and small enough to disappear in a pocket.
