Hi,

I don't know what the Europeans are loading as NATO Spec. ammo, but according to our government's official publications on the matter, we are loading a 121 grain bullet to 1,260 fps. (as shot through a pistol)

According to extensive research I have done, in both German commercial and military publications of the period, the original WWII German 9mm Pistol ammo was loaded as follows: 123 grain bullet to 1,076 fps. (as shot through a pistol)

Just do the math. The U.S. NATO Spec. loading is overloaded by approximately 184 fps or 17%. Though this is not a perfect comparison, I think we can all agree that more "energy" is needed to throw approximately the same weight bullet 184 fps faster.

The implied conclusion, from these facts, is that one shouldn't need ammo overloaded by some 17% to get a Luger to function properly (with an original set of springs, in spec., anyway).

Your thoughts?
