I can see several advantages to open carry. If you have a child walking with you holding their hand on your weak side it allows you to draw without having to let go of the child . This can help if you need to lead the child away from the scene after you have drawn or to keep the child near you. Also you can carry a bag with your weak hand and still be able to draw without first dropping the bag and the raising your shirt to draw. And there is the chance that you can educate someone about firearms by showing them people who own guns are not bad people.Just curious, but what do you believe you gain from open carrying aside from being able to carry a larger gun? A larger gun could still be made "mostly" concealed (at least in a way that would make it less noticeable) by simply wearing one's shirt untucked.
