So what gives you the right to decide which "brand" of firearm is allowed in your class? Just because somebody may not have the cash to purchase a gun that you "approve" of does not make it right to discriminate against the firearm that they are able to afford.
You have the right to stick your nose up and refuse to purchase a "budget" firearm if you so choose with your money, but to refuse to allow a person to use the firearm they will be reaching for in a life and death situation just speaks volumes about the kind of person you truly are.
FOR SHAME! FOR SHAME!!
I, also am an instructor. MY class, MY range, and MY rules. Period. As a certified RSO, I have a responsibility to my students to ensure their safety. I decide which firearms I'll allow in my classes. I do very intensive research on many firearms, and based on that research, I choose firearms that have known issues/defects, and personal accounts, and will NOT allow them in my classes.
