First I want to apologize if the length of my posts taxes anyone's brain capacity.

Bet you all will be surprised.

I'm not Batman, but I can google.
Since you asked:

SAAMI max chamber pressure for 9mm is 35,000 PSI. .357 SIG is 40,000 PSI.
This doesn't seem like a lot, except that the max for .357 Magnum is also 35,000 PSI, and the max for .44 Magnum is 36,000.
So, not only is the chamber pressure for .357 SIG appreciably more than 9mm, it is also significantly more than .44 Mag max pressure.
I'm not sure what part of this is supposed to surprise me. Nothing in the above data contradicts anything I've said. I don't know where the spike is on either pressure curve, but since the .357 SIG achieves higher muzzle velocities with comparable bullet weights in identical length barrels, I would speculate it spikes faster.
Regarding some other issues presented:
Yes, I do believe that a steel framed, single stack 1911 is still a "state of the art" combat pistol. Absolutely. I highly suspect that I am not alone in this belief.
NO handgun is suitable for "running gun battles, and barricades." Period. However, it is not generally socially acceptable to carry weaponry to deal with these conditions. Also, I highly suspect that no one carries enough pistol ammo to engage in a "running gun battle," unless there is a whole lot more "running" than there is "battle."
DeltaII5, could you please explain your conclusion that the 9mm is "useless as compared to .40S&W."
