Watch that video and you tell your wife or daughter to lock herself in a room and hope the police get there in time.
My wife knows, someone comes in the house its time for the 9mm surprise...
I live in a relatively small condo, so there is not really anywhere for an intruder to "hide" the only two viable entry points are in the open. The plan if someone breaks in is for my wife to call 911 gun in hand while I go confront the threat. God forbid I am compromised you would have to be one hell of a lucky guy to have someone who is familiar with firearms miss you 17 times as you came through a doorway at less than 8 feet so at least I know she would safe.
