How many rounds are fired by each side during an encounter with a would be robber?
I would gather that in most cases only a round or two are fired before one side becomes incapacitated.
Therefore, a 5-shot revolver should be sufficient, the manufacturers have been making them for over 150 years now.
As to the modern day comparisons, I wouldn't want to get shot by any caliber! Those comparables have put plenty of bad guys in boot hill.
Studies of gunfights by law enforcement officers indicate that even well trained officers only make about 30% hits in stressful situations.
30% of six shots = 1.8 hits per cylinder.
While many bad guys often do run after only one or two shots from a good guy, real life encounters have seen bad guys still fighting after receiving several torso hits, so it all depends on how determined an attacker is?
While I have never used lethal force, I have been trained by people who have been there and done that on more than one occasion, and IMHO, based on my training, much of what has been disseminated on this thread is wishful thinking based on erroneous ideas.
I would much rather err on the side of carrying too much ammo, for the latest piece of tactical plastic, rather than err on the side of not enough.
There are more than a few vids of gunfights on youtube where more rounds were fired in only a coupla seconds, than one would think possible, with few if any hits.
Here is an article that might be appropriate for this thread.

The old adage of "prepare for the worst, pray for the best" comes to mind, during any of these discussions.
