For what it's worth, using Power Pistol and Alliant load data, it's not far off from delivering 1000 fps with a 230gr bullet, and Alliant doesn't list it as plus P either. It consistently runs 975 fps from my G21, right around 1000 fps from a 5" barrel. Using standard ACP brass I've never had a problem with this load.

Also to note, Hodgdons 45 Super data is a joke, it's literally less than .45 ACP +P, and can (and should) be loaded well into the 30K PSI range.
