Finally had a chance to move my long gun safe upstairs to our bedroom, which is our designated "safe room." Loaded 4 shells of Federal high-brass #1 buckshot (16 pellets) into the tube, left the chamber empty. Six more shells on the butt cuff.
It's a stock Remington 870 Express pump. Might get a shorter 20" deer barrel for it, with rifle sights. Currently has a 28" barrel with a magnetic fiber optic bead on the front. Given that it is a "defend in place" weapon, I feel the longer barrel is ok, for now. The kids' rooms are all upstairs, near ours, so no need to clear the whole house. I'd rather defend in place, let the BG(s) come to me - and let the police clear the home.
We have a GunVault next to the bed, with several handguns in it, and the key to the long gun safe. My wife would grab the kids and get them to the bedroom, while I covered her with the Glock. Once in the bedroom, if time permits, I could get the shotgun.
I've always wanted to keep the shotty set up for home defense, but needed a way to keep the kids away from it. This should do!
