Things like those charts, the "rule of threes", etc, that are often thrown around and usually by those who choose the smaller guns and feel they have to justify why they carry it.
Hey, carry what you want, but the reality is, no matter where you are or might go, you have absolutely no idea as to what you might get, and you're going to have to deal with it as best you can with what you have.
Hopefully, its enough, and you're as good as you say with it in that sort of shooting environment. Having the gun is one thing, being realistically capable of deploying and using it without thought, is often something else.
Youre just hoping if something does go south, its going to fall into one of those "statistical" groups on a chart, and/or one of the narrow scenarios you always win in your mind.
If you're the least bit serious about this, I would think you would choose the gun that you shoot the best with and shoot the most in regular practice with, and from how you carry it (not just standing there, squeezing off the basics at bullseye or can). And then carry it every day.
Unless of course, you have one of those Magic 8 Balls.
Even then, my guess is you'll still choose the wrong gun.
