My mother in law wants to attend ccw class with me. She has not fired a firearm in decades and the main purpose she wants to attend is to understand hand guns and prepare for situations. My concern is that a ccw class would not serve her best. My other concern is she wants to use my Walther p22 to learn. In my opinion this is not a good gun to learn with. I think she would be better off starting with a revolver. Any thoughts?
