Actually, it gets even better than that.
The Rohrbaughs continue to feel Shelby's breakage was an isolated case. If, however, any current owner wants to change their pin to the 17-4PH pin, and not use the old pin made from 440 stainless, just contact the factory and they will gladly switch the pins. Rohrbaugh would ship the pin to you and ask for you to return the 440 pin, and then update your serial number in their records as having the 17-4PH pin.
As for me, I plan to stay with the 440 pin unless there is news of other breakages.
Thanks, guys!
