Agreed, you never know what the situation will be when that nasty moment arises. I just don't think it will be a long drawn out shootem up like on TV. Shooting through a wall or car door has pros and cons as does a 10mm with even more penetration.
But I have to always think about "what gun might they have", I don't want to be disadvantaged and don't want to contend with shooting "walking" wounded.
But better to have a gun you will carry, you will shoot, and you can hit with regardless of how it looks on paper.
