Brenda from Ruger customer service called me today about the 44 spl I thought was flame cutting. They tested the frame and it was properly hardened. They next pulled the barrel and found that the die used to cut the reciever threads did continue into the backstrap. So they said they are going to reinstall the barrel and refinish the pistol. I should have it back sometime next week. This is a wonderful relief because I really like this Blackhawk and I gained much faith in Rugers customer service.
