Few men know how to knife-fight or anything about it. Only in the movies does someone fall down and dies instantly from a knife wound. I know where the effective targets are in the human body, subclavial arterys, carotids, femorals, kidneys, etc., and I would not use a knife if a gun were available. Use the handgun and be done with it.
Sometimes you get what you pay for, sometimes you only pay more for what you get.
Three shots are not a "group"...they are a "few".
If the Bible is the literal, infallible, unerring word of God...where are all those witches I am supposed to kill?
