Does a pistol on my hip give LEO sufficient suspicion to ask for my permit to carry, or submit to a pat-down after I tell them who I am?
Depends on your state. If you are not in an open carry state, then you are breaking the law and they can arrest you and ask you for ID, carry permit, just about anything. If you are in an open carry state, then no. You may have to tell them who you are, show them ID, or nothing depending on your state laws.
