Pat, I don't like either of those terms since to me a gun slob is someone who doesn't hunt or shoot a lot and is not safe to be around when they are holding a gun. A gun snob is a self serving, self aggrandizing, smarter than thou David Petzal types, unlike John Wooters, jack OConner, and John Jobson.
No, those are just average, everyday slobs and snobs. Unfortunately some of them own guns. We don't have to look far for those.
