I agree ... and I would pray I never needed to find out ... but ... here's the rub, if I find myself in a situation where I needed to make the decision to shoot ... and can't ... I don't think I'm any worse off than not having a weapon ... JMHO ... and worse case ... I'm pretty sure if some one got close enough .. I could hit them with it like a hammer.
Don't carry a gun you if have doubts of using it. It could end up being used on you. Don't point a gun at anyone you can't or won't shoot. If you let them get close they will own that gun in a heartbeat.
