".357 is effective, but it does have a kick. I think it was designed by Elmer Keith...What’s especially nice about the .357 weapons (revolvers) is they will chamber .38 special, useful for training as the kick is less, and the expense."

Different .357. The SS has used the .357 Sig, which is an autoloading round based on the .40 S&W case necked down to .357.

Actually, the .357 Sig is based on the 10mm,not the .40 S&W.
The 10mm case has thicker walls to handle the increased pressure.
