If your gun were an old field grade I would not worry it much, but given it is a more expensive proposition and the barrels were thinner to start with than a heavyweight field grade I would send it to a good gunsmith and have the issue fixed before it creates an even thnner spot.
I agree with Bilious Bob that who you send it to is vital.
The investment in a Purdey demands no chances to taken with a gunsmith who is not the best grade proven man.
Both JJ at Champlain's and Kirk Merrington are such men and I have had work done by both. They are excellent and will properly care for your gun. You could add Keith Kearcher to his list.
