In America, shotguns hava place in our psyche.
This dates back to the 1800's stagecoachs when the right hand front seat passanger "rode shotgun":

The best guns in personal defense are easy.
Start with a 38 caliber or 9mm, super reliable gun like a Glock or a revolver using hit splatter bullets.

Then supplement it with a 12 gauge full choke shotgun with a 4 round load.
Grab your handgun, until you can get to your shotgun!
Every burglar knows the sound distinctive “ka-click” sound of a shotgun being chambered.
If they don’t skedaddle after hearing a shotgun being loaded, then they are very bad people and need to be killed before they kill you.
The police told me to use the “21 foot” rule, whereby a bad guy can get to you at 21 feet before you can draw your handgun and fire.

Remember, the primary purpose of a home defense pistol is to give you enough time to get to your rifle or shotgun.
A shotgun is a far safer gun for home defense, they are lethal with less accuracy needed . . .
