Inside your typical 2x4 and drywall house, anything 9mm and up is more than viable. I was once on the receiving end of a guy shooting through walls with a 9mm Glock, 40 caliber Glock and a shotgun loaded with birdshot. All three went through multiple walls like they weren't even there. I guess I'm glad they weren't .223 rounds because I was wearing a IIIA vest at the time but that's really splitting hairs considering any of those rounds could have hit me in the face.
Nothing wrong with 9mm PCC for home defense in my view. My PCC is a lot quieter than my 11.5" BCM, I really wouldn't want to fire that indoors without hearing protection.
