Saw this P38 from GB and notice the font difference between the slide, frame, barrel and other part. Noticeable is "3" and "P" in serial number. Is this all matching gun legit or fake? I'm still learning to distinguish fake ones through those turd alert threads, that's how I noticed the font difference, but not sure if it's possible some parts were made by subcontractor but then wouldn't parts made by subcontractor only stamped after the part was fitted in the gun by the primary contractor using their stamp instead of stamped at subcontractor's factory using subcontractor stamp? Also what's that marking of eagle with an X in the circle with "C" next to it?
