A guy open carrying a Glock walked into the place I used to work. I was curious, and asked him how he liked being in law enforcement. He replied that he was not in law enforcement. I said, "I noticed your Glock". He said, "oh yeah, I have a carry permit". I said "I do too, but I conceal it". He then went on to show me a Georgia firearms permit, and said, "where does it say you must conceal the firearm on this permit"? I said, humm, "OK, well, have you ever had any problem with the public, or the police"? He said, "no, I have only had one problem, I was asked to leave Walmart one time". We talked a little more about guns and such, and he bought his items and left.
I have no problem with someone open carrying their weapon, hell, were I was born, up until 10 or 15 years ago, everyone open carried, and there were no problems. I would rather conceal mine though, due to tactics. Why would you want the criminal to know that your the one to shoot/attack first?
