All my bedrooms are upstairs. If someone actually breaks in, which is an exceedingly small possibility, wife will barricade in a room with the kids and I'll be posted at the top of the stairwell with my 1201FP , she will have a pistol. Either way, the stairwell lights will come on and anything that even pokes its head out at the bottom of the stairs will get a face full of #4 buck. Hopefully turning the lights on would be enough of a deterrent for them to leave.
So...why do I need to spend $130 on a WML
