I wish that is what it stand for too. But it is far from the reality. All current production 1911 now has NM pre-fix, but they are average production level accuracy and will not be possible to achieve National Match level accuracy unless going through some custom works.I was always under the impression the NM did mean National Match (some models had a two piece barrel, others the NM barrel). And the WW was indicative of the World War (2?) or GI model.
