.357 Mag vs. .357 Sig

The two cartridges have nothing in common other than the number in the name and velocities with like bullets. You may or may not be able to easily find .357 Sig ammo and brass or a pistol chambered in it.
The .357 Sig is a rimless, bottle necked, cartridge that uses .355" bullets. Velocities are in the 1300 to 1400fps range with a 125 grain bullet.
The .357 Mag is a rimmed, straight walled, cartridge that is 1/10" longer than a .38 Special. Its bullet measures .357" and can weight up to 168 grains.

If you are looking for a semi-auto in .357mag, you are going to be looking at a select few. There may be only a half dozen companies that make a non-revolver handgun in .357mag. IMI Desert Eagle jumps out at me, but you are looking at decent coin for that. If you are looking at Revolvers however, almost all can be chambered for .357mag.dpo2o said:

.357 mag is a revolver round
.357 sig is a pistol round that was created to reflect the .357 mag, but in the pistol
.357 sig is more powerful than 9mm luger and majority of .357 sig pistols can be converted into 40 S&W by changing/swaping the barrel only.
"...you are looking at decent coin for that..." And you need big hands.
"...a pistol that is chambered for..." The term 'pistol' is generally considered to be a semi-auto these days. Is that what you're looking for? Or do you just want a .357?
Buy yourself a Ruger GP-100, do a trigger job(they all need one due to frivolous U.S. liability law suits)and have fun. I've had mine since they first came to Canada. It's the only revolver I've ever had that did not need a change of grips to fit my short wide hand.
When you get that far, you can shoot .38 Specials out of it, but it's better to load .357 brass to .38 velocities. A diet of cast .38 Specials will leave a ring of lube gunk in the cylinders that must be cleaned out before shooting .357's. Loading cast bullets in .357 brass eliminates this.
