“We already have the 12-gauge.”
What worries me about shotguns indoors is hearing damage. OTOH, better than being dead, I suppose.
Ha...if you are in a firefight, you'll never hear the blast. Auditory exclusion is a real thing. Yeah, you'll have hearing damage, but will only realize it after the adrenalin rush from near death subsides (unless you go into shock).
You'll probably notice the crap in your pants before you notice ears ringing....and any one that's been in a firefight and hasn't personally experience "blowing of the ballast" of themselves or their buddies is lying to you.
WHAT !!!!
