In my humble opinion, it depends very much on the grade of the Pieper. I've seen a few that were very roughly finished. Then again others have been very nice...It appears the large manufacturing enterprise of Pieper made guns to cover a wide spectrum of price points; but again that has just been my observation. If all things are equal, condition, finish, weight, features, etc, I would sure choose the gun with the better fit. I think that would make all the difference in your enjoyment of the gun. "Pretty" doesn't always break clays or knock down birds, even if it is pleasing to the eye. If its a gun you plan on using rather than collecting, fit would be my personal deciding factor.
Your mileage may vary...
