I think AA#7 was originally formulated for the 9 X 19. It's a great powder for 9mm performance ammo, in the same ballpark with VV 3N37, Longshot and Ramshot's True Blue.
In Accurate's data, the 115gr bullet lists 29,700 CUP for an 8.8gr max of #7. That's well under SAAMI's old 33, 000 CUP for regular pressure 9mm. You also get a low flash to go with it.
