A fella approached me a few years ago in a warehouse I was working in. Being from Detroit he was a little hesitant to talk freely about self defense and had to pull me aside for questions about what handgun to get.
I suggested he start with 9mm and take a training/CC. He asked about 25acp and i said they weren't known for being an effective threat stopper.
"Oh no, man...I don't wanna kill the dude, jus' scare him".
