For the folks that say they need to see their holster, I guess you never carry with a SOB holster?
I think you are missing the point. It is not so much to "see" the holster as it is to be very deliberate re holstering. I am fairly new to Glock's but have a career of being a gun toter. I do not often carry strong side hip OWB concealed and never SOB due to the possibility of a back injury.
