Ultimate home defence pistol?

Truthfully the argument over stopping power is comical. I don't want to get hit with any round. It's what you can operate under stress(half asleep). For me instinctively... it's shoulder fired.

I own damn near every caliber of "assault rifle" made. I have no interest in lighting up a house with 300 blackout, 7.62x54, or you name it. I don't have neighbor concerns, but I have no interest in blown out ear drums, ect. A shoulder fired 9mm is fine with me. It's almost cute to handle, but I sure as **** wouldn't want to get hit with it.
