Hi folks.
What's .357 Auto?
Not .357 Sig.
S&W makes the M&P in .357 Sig and in .357 Auto.
ballistics? Who makes .357 Auto?
Thanks in advance.

    Yup, .357 Sig.

    Some manufacturers still don't like to put a competitors name on their gun. You'll sometimes see ".40 auto" instead of ".40 S&W", .357 Auto instead of .357 Sig, on and on. Way back in the old days it was common for makers like Winchester and Marlin to re-name "calibers" in their own name instead of using the original name. An example like ".32-20 Winchester" would be marked on a Marlin ".32-20 Marlin", with the only difference the bullet weight, headstamp, etc.

    Good caliber, and the M&P is a good gun.

    There was also a .357 AutoMag ctg. made by necking down the .44 AutoMag - these were based on the 30.06 family of cases, shortened and reformed. Check AMT AutoMag, Wildey Firearms and Catridges of the World for description & load data.
    It's being willing. I found out early that most men, regardless of cause or need, aren't willing. They blink an eye or draw a breath before they pull the trigger. I won't. ~ J.B. Books

    From his question, I doubt that the 356 Automag would be applicable here as S&W never made the M&P in that caliber.

    Smith uses the term "357 auto" to refer to the round otherwise known as "357 SIG".

    Its not clear to me why Smith doesn't use one term consistently, but it doesn't.

    I think Smith does this in part because Smith, in particular, is know for building .357 magnum revolvers. In fact, the proper name for the cartridge is the ".357 Smith and Wesson magnum".

    Since the M&P brand name was historically associated with REVOLVERS (in particular the K-frame .38 later known as the model 10), I could see why it might want to use the term "auto" when referring to the load in this context.

    Also, as mentioned, one added reason is just not to give props to SIG, a competitor.

    Note that lots of companies label their .45ACP guns ".45 auto" and .40SW ".40 auto". That's the new convention.
