Still more frightening are those that show up for the Concealed Carry Class and load their ammunition in the magazine backwards. That is why I offer a reduced price for my CHL class to those that have completed my Basic NRA Pistol class.
My favorite was the guy who was pointing his brand new Kahr PM9 at me in the next lane as he is looking for the safety. . . . that gun has no safety. He even asked me if I worked there and could tell him where it was.
