Here's another tidbit from the same Highroad thread.

The problem is that seeking a "NATO Spec" is chasing something that does not exist.

The governing document for 9x19 ammunition is STANAG (Standardization Agreement) 4090, which addresses ammunition interchangeability, including cartridge dimensions and barrel dimensions, but leaves a wide scope in the ammunition itself for national preferences.

See: http://www.scribd.com/doc/60112455/S...Cartridge-9x19

Briefly, bullet weight must be 108 gr. to 128 gr.; muzzle energy NLT 400 ft. lbs, NTE 600 ft. lbs.; working pressures NTE 37,000 psi; maximum NTE 42,700 psi. Muzzle velocity is not addressed, nor is any minimum pressure, except that it must function the approved weapons.

In other words, the STANAG is a performance and interchangeability spec. They didn't care about details as long as every round bearing the NATO symbol would work in all NATO weapons without damaging the weapons, and would give the required lethality.

These guys are not focused specifically on Lugers, but the link to the actual specs might be useful. Not that this guy's interpretation is necessarily accurate, but it does give the impression that the designation 'NATO" is a little more elusive or complex or inclusive than one might imagine.
