When you attend instructors school of any type they talk about modeling. You look, act and speak the way you want your students need to in order to be successful doing what you are teaching.
As with all things especially a pistol course for CCW you need to cover the Selection, Carry, Deployment and Use of the pistol. The instructor in question already showed that he is not competent to teach the carry part. That would be enough for me to go somewhere else.
