My girlfriend has never shot a handgun, before, and I want to teach her how. Should she start with a .22 revolver, or a .22 automatic? I know the revolver would be simpler, but it's not like selling a defense gun to someone in a gunstore who you have no idea whether or not knows how to use it; I'm fairly certain I could teach her the basics of an automatic. On the other hand, the autoloader wouldn't transition directly to a usable defensive arm. For instance, a S&W 617 is functionally Identical to a M19, except for caliber, but a Ruger MkII is a lot different than a Ruger P95.
