+P 9mm ammo penetrates deeper than +P+ because the bullets over expand at the higher speed of the +P+. The 357 bullets are designed for the added velocity. The 357 Sig looses 2 rounds of magazine capacity to the 9mm, the same as the 40 S&W does.

THIS

The added velocity of +P or the .357 Sig is more about barrier penetration.
