The BEST home defense weapon is....
The one that you have next to you when you need it!!
I carry a pistol pretty much everywhere and when at home.
The ONLY time I don't have a pistol on my belt is in the shower and when sleeping in bed, but it sits on my night stand.
Practice and be ready.
LOL, This was actually done for the Manufacturer of the block and it was used by them, I don't know of Brownells ever used it, this was done years ago and I lose track.
