Yes, that would be my guess. I wouldn't worry about it, just enjoy it for what it is.
What sort of chokes does it have? Tight and tighter, in typical German fashion?
A quick check with my plug gauge said Mod/full, but I have been meaning to mic them to find out. Not that it matters, both barrels have killed pheasants, sharptails and ruffed grouse on the fly, so I am happy!
Going to try and kill a white tail with it this week.
