Wow, which one to answer...
Eenie, meenie, miney, moe, when the timer hollers go, grab your gun & let it show, eenie, meenie, miney, HEY MOE!
Sorry, it's late, and I'm a little punchy...
Ok, back to your question.
AFIK, the standard German loading was a 124-gr. bullet going about 1,300 fps.
Although it has been widely bandied about for years that the Germans had two separate loadings, one for handgun, one for subgun, that's not the case.
The current NATO loading is, I believe, is done to the same specs as the old German load.
