How do they compare in terms of recoil and stopping power? It looks like the .357 SIG has less powder behind it than the .357 magnum. Does it have a slower muzzle velocity? Is it as lethal as the .357 magnum?

It was designed to match the performance of certain weaker .357 magnum rounds I believe. The stronger kind of .357 magnum loads pack more power than the .357 Sig for sure.
It's a high velocity pistol cartridge compared to the other popular ones out there. The idea was to get the performance of slightly below average .357 magnum loadings in a semi-automatic pistol. Though there are some, revolver cartridges for the most part don't work well in semi-automatic pistols, they're too long and they are rimmed.
Like the guy above said, it's pretty fast so it will penetrate more then many others. It's becoming more popular though I think, a number of pretty large law enforcement agencies have adopted it as their standard cartridge. A lot of .357 SIG pistols are interchangable with .40S&W by only swapping the barrel, this isn't always the case though.
As others have said though, it's quite a bit more expensive than the most common rounds like 9mm, .40SW and .45ACP.

The .357 SIG has some advantages and disadvantages. It is a very 'hot' round and will wear out guns faster than say a .45acp.
It has extreme penetration properties. This is both a good and bad thing. For a home defense round, it's pretty dangerous as it will go through many walls. As a tactical police weapon where it is expected that an intended target may be in a vehicle or wearting body armor, it does it's job well.
If you are considering it, remember how expensive the ammo is....
Read the WIki article....it seems accruate and has a lot of facts.

The .357 Sig is a necked down .40 S&W case loaded with .357 diameter bullets to be shot out of semi autos chambered for it. They are not cheap in facory rounds, and I would not recommend this caliber if you do NOT reload your own ammo. From a short barrel of most semi autos, median velocity is slightly above 1200 fps. .357 Mags shot from a 6" revolver averages over 1375fps. Out of a 4" barreled revolver , about 1300 fps. Fired out of a 7 1/2 to 8 " barrel, the .357 exceeds 1400 fps easily.

I consider it to be a less than successful effort to get .357 Magnum power in a semi-automatic package.
Other than the 125 gr. JHP, they have not succeded.
While the .357 SIG offers magnum velocity and energy with the 125 grain bullets, it lacks versatility. There are no 158 grain or heavier bullets available, nor are there 10 grain bullets available either.
Given my druthers, I'd prefer a 4" M-686 or M-19 revolver.

the sig is a little smaller, and design for use in tactical semi-auto handguns. It compares favoably, but because most semis have shorter barrels muzzle velocity can be greater with a mgnum in a long barreled revolver. Mags are cheaper rounds to buy because there are more manufacturers and also many many more types and weights of bullets available, on paper the mag is a little more powerful but in action both are more than adequate as manstoppers. pick out the gun that will most suit your needs and you can't go wrong with either cal.
