I found the same thing on my new NRM SS 1991A1 Government model. Not a big deal. Only other thing I've noticed is that the trigger "jiggles" a bit side-to-side, although not enough to really bother me.Rrotz said:There is a small amount of metal shavings inside, that I'm cleaning out. There are virtually no machine marks inside, that I can discern.
All-in-all, I'm really happy with mine and I'm sure you'll be as happy with yours!
