The “rack your shotgun to scare away the bad guy” meme is getting really old. Has anyone actually seen this work in real life? In 6 decades of life I’ve never heard of it. If I’m engaging someone, especially within my home, my strategy is stealth and concealment followed by all hell breaking loose.
Other than this and recommending a .410 pistol for home defense his recommendations are good, but not exactly new information. I’d add that in a SHTF situation it’s best to have firearms in calibers that are in common military use.
