in the real world good shot placement, although hoped for, very seldom happens when the shooter and the shot are in motion.
I have seen what those calibers do on animals and the results are quite different, especially the sig.
9mm ammo is the least expensive of all of them, but ammo price is not even in my top five of reasons to choose a caliber. I have chosen 9mm because I have a G17. If I had a G22 I would use .40 S&W.
