I'd imagine any gun won't feel like enough when a gunfight happens.
As it's been, I didn't need to shoot and the snubby sufficied.
The idea that 3-4 guys are going to stand around stoically while you empty your gun into one of them is also a bit of a sretch, be it a snubby or Mac 10.
I carry what I can, usually it's a five shooter.
The West is the Best.
