Need some advice here folks, I have a family friend and she's in her 50s/60s and has her CHL. She just asked about a .22 to carry while walking but doesnt want to shoot to kill. I'm wholeheartedly against this idea. if you need a gun, then its life or death, at which point you shoot to kill. In my opinion a .22 is pretty likely to just piss off some crack head (She's in Memphis) and make matters worse. Any advice on how to respond?
