I think we're forgetting some of our basic tenets here. All guns have the ability to kill. Some might be more likely to kill than others, but all firearms have the ability to end a life with a single shot.
Granted I'm preaching to the choir here, but I think that's important in any "is this caliber powerful enough for ____" discussion. Even a .22 short can stop an attacker... although I certainly wouldn't choose that as my carry weapon! We're always riding that fine line between adequate power, capacity, size, shape, weight (concealability/carry-ability).
I prefer .38spl +p and 9mm in my carry guns, as it seems like a decent compromise to me. .22LR would be way too small, and although I like larger calibers, I don't find many guns in .45ACP that would fit my needs for carry. That's my own personal opinion.
Aside form the reliability questions that rimfire cartridges bring, I do think that a pistol like the PMR-30 could be good in this role if the shooter was well trained with the weapon. Multiple hits from a .22 Magnum would be quite a discouragement to an attacker, methinks. It's just a case of trading power for capacity.
In the end, pistols are pistols. No handgun is going to be a 100% reliable "manstopper." There are just too many factors in play, handguns are a compromise by design.
