I don't know if I would open carry if it were allowed in TX, but I would be less concerned about accidentally exposing my CCW. Not that I am really all that concerned anyway since I carry a J-frame or LCP, but it would make it easier for me to carry a larger gun if I wanted to and not worry about exposing.
This is my gun. There are many like her, but this one is mine.
