True, a NAA mini revolver is better than a sharp stick or carrying nothing at all.The best choice is the one that works for you, that you shoot well and are comfortable with. Knew a guy once whose carry gun was a NAA .22 short revolver. It was his better choice.
But if I carry a gun so that I can defend the lives of me and mine in a fight for our lives (which I think most people do), I want the best tool for the job (within reason, because someone is going to ask where I carry my Seal Team at lol). I'm trying to stop bad guys from doing bad things, not fighting squirrels.
