I don't know SOG, but I've had P38's. I looked at their web site. Where did they "just find" these guns? Nazi marked, has come to mean that they have eagle proof marks on them. (meaning gun was tested with ammo 20% over standard issue). For over $500 I'd expect a '42 or '43 marked gun with all matching serial #s, and perfect grips. If you buy one get all new springs. Save your money don't by one.
