Back in the 1970's when I was in pharmacy school, I had to work part time - usually in pharmacies in dangerous neighborhoods during the evening or night shifts. The only two handguns I had where are Ruger Mark 1 semiauto pistol in 22 LR and a Ruger Super Blackhawk 44 Magnum...
......choices, choices.....
So..... I purchased a Bianchi X-15 shoulder rig, and wore that under my cute little white coat I had to wear as a pharmacy intern.
What made that especially interesting was the fact that at that time, Ohio did not allow concealed carry at all, even though it was legal and within the intent of the law. What had happened was over time the idea that one should not need a permit to carry, but just simply not have any of the characteristics that should prohibit it, such as being a felon, intoxicated, juvenile, acting recklessly, or committing a crime, had morphed into the idea that if you carry concealed you would get arrested and have to 'prove' that you weren't doing anything bad. Guilty until proven innocent. I'm sure that had I been caught carrying concealed there I would have gotten in quite a bit of trouble, probably thrown out of school and in to jail. If I were in a similar situation now, I would definitely carry a much more concealable firearm, but that's all I had in those days...!
