The outer dimension of the .357Sig, and I'm certain the .40 too - the firearm itself - is very slightly fatter than the 9. Not enough to affect its concealed carry, but enough so you're not going to be jamming a fatter magazine or a larger-diameter barrel into the 9. This would be to accommodate the bigger cartridges. Just make sure you know what you're getting when you order.

That's weird. Most other guns, the only difference between a 9mm and .40S&W is the barrel and magazine since the overall diameter difference of the two rounds is about 1mm.
Should be noted you can go "down" the spectrum with a Sig though. If you have a .40/.357 you can get a 9mm barrel for it. Bar-Sto makes some.
