I have been stopped multiple times by police while armed. In every case, I keep my hands still and ask permission to reach for anything. That is all that most officers want.

Hands are dangerous. They are trained to watch hands. When hands are moving, they are trained to react to the hands not the item that might come next.

When officers tell you to stop moving your hands, comply. Refusing to keep your hands still will cause a lot of issues for both you and the officer.
