There is no SAAMI standard for 40 S&W +P but that hasn't stopped ammo from being sold under that term. There is however 45acp +P brass, ammo and an official SAAMI pressure ceiling for it.

I always found it ironic when people are reluctant to use +P brass for anything but reduced power load, given that it is either the exact same as normal brass or reinforced to handle extra pressure. You would have to contact the manufacturer of the brass to know which it is as SAAMI only specifies external dimensions.
