I suspect most would scoff at this...but is it necessarily such a terrible idea? My thinking is if I hit an intruder with a .22, no it won't do as much damage, but I'm thinking it's more about making contact at all vs how much. Getting shot with even a .22 won't exactly tickle. Most intruders are trying to rob you for whatever and even the "lesser" damage caused by a .22 is probably more than it's worth. This isn't a Clint Eastwood movie. Also in most situations, it's not like I'll have the luxury of assuming the "proper stance" (etc) to fire the gun, I might even need to fire it with one hand. Given that, the far lesser kickback of a .22 has its appeal. Is that crazy talk? Or a viable consideration?
