i have a springfield that i bought new in early 2000. i think it was a older production gun, anyway it has a NM prefix on serial number and no brazilian markings anywhere. i haven't seen any others with the NM an fellow at the range was saying it was a national match gun, i feel he is full of poop. whats up with the prefix? also this gun had a satin stainless finish, ext.thumb safety and slide release, wood grips and mil spec sights and and grip safety, it also had the old style rear cocking serrations. is this an odd equipped gun or standard issue for the time?
