It seems odd a manufacturer would label an ammo box with a designation that doesn't technically existing in the SAAMI specs list, "38 Super".
Doing a search I was only able to find one ammo box's end view which was labelled with only "38 Super", Fiocchi, but end views are hard to find though.
Since standard 9x19 max pressure is 35K psi & 9x19 (+P) is 38.5K psi, I don't know how someone could gain anything meaningful from that labelling since 38 Super +P pressure is 36.5K psi, SAAMI pressures. (38 Automatic pressure is only 26.5k psi.)
