Guess I better do some research on how autos work, and what force exactly gets the slid moving.
Recoil. See Newton's third law.

Yeah, I was thinking about it last night, and it now seems obvious. I don't know why I though pressure was involved in moving the slide, but I did.
So, I think the slide must begin to move before the bullet leaves the barrel.
Regarding the bottle-neck configuration that the .357 SIG has, I recall having read a few opinions that it has an inherent propensity to feed more reliably from magazine to chamber than typical straight wall-cases do (whether, if true, that's a "practical" advantage or not is hard to say but anything that contributes to the reliability of a firearm intended for self-defense is always a plus).
