The .357Sig is a necked down .40 with a 9mm sized bullet. It has more muzzle blast and flash than a .40 with about the same muzzle flip. Has more energy coming out of the barrel than the 40 and supposedly penetrates better in car doors and windshields. It is easier to shoot and handle than the .357 magnum. The .357 Sig is a fun round to shoot but can be a bit pricey.

You get about the same ballistics with an updated platform. You can find a wide variety of semi auto handguns from various manufacturers in the .357 Sig. There were not many .357 magnum autoloaders built.
