Herb,
As taken from multiple original German texts of both WWI and WWII, as well as, commercial texts of that period, German Army ammo was standardized at:
123 grain bullet (either truncated cone or the later round nose) at a velocity of 1,076 fps.
Current 124 grain NATO Spec. 9mm is much hotter, ranging as high as 1,261, as fired through a 4.5 inch pistol barrel (an approximate 17% overload as compared to the original German Army loading above).
Shoot modern 9mm NATO ammo through your Luger at your own risk!
