Ultimate home defence pistol?

Ok, I'll be the guy to derail things. For home defense I wouldn't grab a pistol. I prefer a shoulder fired weapon when possible. I have a Berretta CX4 storm(chambered in 9mm). Light weight, incredibly fast target acquisition, decent capacity, ect. I like pistol caliber carbines for close quarters.

My pistols are for duels at gas pumps. My shotguns are for birds. My scary guns are for libs. My bow is to fill my freezer with deer and turkey....but I'll take a pistol caliber carbine to defend my home.
