Correct, all the .357 Sig, is a .40 S & W necked down. Whether the conversion barrels are available on the commercial market is another consideration though. Many handgun manufacturers will not sell the barrels for conversation, they would rather that you bought separate pistols chambered for each caliber. When I bought a .357 Sig barrel for my Glock .40, had to get it from a aftermarket dealer. 0 -
SIG has sold their conversion barrels for years. Most of my SIGS are in dual calibers, but not sure why. I never bother shooting 40 S&W[:D] 0 -
Rufe has it.
357 SIG is, in effect, a standard 40SW necked down to take 9mm bullets. Most .40SW guns can be converted to 357 SIG just by swapping the barrel and doing nothing else. In most cases you can use the same 40SW magazine too.
The idea was to get something like .357 magnum revolver ballistics, but out of a standard platform high capacity .40SW semi-auto gun. At about 1350 fps with a 124 grain bullet (compared to about 1450 fps with a 125 grain bullet from a .357 magnum), you do get reasonably close here.
If you can find one for sale, the SIG conversion barrels should run about $200-240. Whether or not its worth the conversion is a whole other matter.
My personal take is that while the 357 SIG is itself a good round, empirically, its not THAT much more powerful than hot 9mm luger +P loads. You can also get reasonably similar ballistics using lightweight bullets in a .40SW.0 -

just shoot 40 S&W Semper Fi0 -

40SW is not only a little cheaper than 357 SIG, but its also usually easier to find.
For what its worth, if you like you can put in an aftermarket barrel and convert your .40SW gun to 9mm luger. You'll also need a 9mm luger magazine, and you probably have to swap the recoil spring too.
9mm luger offers less recoil, plus it will let you practice a little cheaper.
Bar-Sto offers this particular conversion barrel for $205, and in general makes an excellent product:

Except for your lack of experience with Sig pistols; your Glock-tainted answer would be correct. How's that Lone Wolf workin'?
Also, TRY necking down a .40 to make a 357Sig; you wind up with a case shorter than you started out with, and will run into excessive pressure when you do. It is actually a trimmed down 10mm you'd need to start with.
Moose has it more nearly correct.0 -
SIG manufactured P226 .357 SIG conversion barrels can be purchased for around $160-$170.
I agree that it would be nice to have a brace of various caliber barrels for a single pistol, but a ,40 S&W or .357 SIG model can't be converted to 9mm due to breechface dimensions. EDIT: This is per SIG- Sauer.
usmcaz- A minor point (and your's might have the older markings), but they're no longer known as SIGARMS. Their US branch is now also officially 'SIG-Sauer'.0 -

You can go from 40/357 to 9mm. (But not 9mm to 40/357) All it takes is a Barsto 9mm conversion barrel and 9mm mags. The breech face is fine and the extractor on these type of firearms springs over far enough to catch the case head and extract reliably.
I do it all the time with my P226 and it is 100% reliable.
