I'll jump in since I actively carry both open and concealed:
I own a number of rental properties, many of which are not in the best parts of town. When I am working on my properties (usually alone), I am wearing shorts and a t-shirt, sweating heavily. I find CC'ing in those conditions to be uncomfortable at best.
additionally, when I first bought one of my units, I had several neighborhood youths approach me to express their displeasure at find some "rich white guy" had bought a foreclosure, "stealing" someone's home from them.
Shortly thereafter, I began to carry,. openly at first, because my CHP had not come in yet. I have continued to open carry in large part, because I do not want any trouble, but I need to be prepared for it.
As a result of OC'ing, all the neighbors know I go around armed. That makes me a hard target for anyone thinking they can grab a little cash at rent time.
Since most of the robberies tend to be strong-arm, with mutiple BGs, I believe it has been an effective deterent. NO matter how many gang-bangers there are, if they aren't armed, they aren't going to pick a fight with someone they know is.
Additionally, even if they are armed, the last thing they want is a gun-fight. they want someone who will cower at the mere sight of a gun.
I don't always open carry, because as a REALTOR, most of my clients are sheeple, and when I am trying to do business, a 2nd amendment debate is rarely the best way to get their business. Additionally, dress in a collared shirt and sports coat at work, and without strapping a thigh hoslter on, it would be difficult to OC.
Instead, I simply wear an IWB at 3 o'clock and if, for whatever reason,. I get made, it at least in not the first thing potential clients have noticed/learned about me.
