I wanted something I can keep in a drawer for fast response. If the kid finds it and shoots himself.. Well let's just say that he should only do that once!
The backup for these is that it turns into a stun gun once shot. YOu just press the barrel against the person and it shocks the crap outta them again.
My 12ga. is in a safe, I just want something I can leave out and not worry about my kid finding. But rest assured, by the time the shock wears off 12ga. should deter any further agression!
