SAAMI sets the MAP (max avg pressure)… for 9mm that is about 35,000psi. +P is about 38,500.

SAAMI doesn’t really address the +P+ stuff to my knowledge

The +P for me always did a little better for short barrels under 4” but I reload most of it anyway. Just an observation after shooting snubbed guns with +P. I don’t have pressure equipment to say what my reloads really do honestly.
