Oc by Permit if that's what you really want,I personally don't see why anyone would want too! If carrying it's more strategic to have your sidearm concealed,that way no one knows if you have one or where it is,so it gives YOU the edge!The element of surprise!
When you Oc a BG knows exactly where you gun is and can make his grab for your gun at any given time,waiting for you to be at your worst moment,when you get inattentive for a few seconds we all do it,you can't say,you don't,that's all they need,and a BG will take his time to follow you for any length of time just for that moment! In my opinion OC is just showing off your gun.LEO and Military have to,they have no choice.Civilians have no need to OC there's no real reason for it,if there was an advantage to OC don't you think undercover detectives would use it?Sorry,I know alot will disagree,but to me it's just to showoff,look at me I have a gun on my hip,I'm a cowboy type mentality. Just doesnt make sense to me when you can CC.
