I'm working in the store today and a woman walks past me. She's wearing a bright pink blouse and black slacks. I notice that she's carrying a Glock at 3 o'clock. At 9 o'clock she's carrying a magazine case with a spare mag. It's all OWB just hanging there for the whole world to see....a black Glock in a black holster on a black belt worn with black slacks. I asked a couple of my fellow employees who were standing near me if they had noticed the woman with the gun. Eyebrows shot up at the mention of the word "gun" and they started rubbernecking the store. "No, where? Where? Where is she?"
And that has pretty much been my experience with open carry. Unless you make an effort to be noticed, you probably won't be. Take that for what it's worth.
