All clients are informed, in writing, of the more stringent requirements and are free to seek certification from a multitude of other instructors.
Missouri law states that an instructor "shall not give a grade of "passing" to an applicant for a concealed carry endorsement who:
...(2) Handles a firearm in a manner that, in the judgment of the qualified firearm safety instructor, poses a danger to the applicant or others..."
In light of the nebulous wording of MS law, your requirements are proper.
You're right, anyone is free to seek other training, and some probably do.
Mr. Glenn E. Meyer, I find your posts and thinly veiled comments to me to be personally sarcastic, argumentative, and provoking. You are arrogant, egotistical, and rude. And ignored. Bye.
