I would take that advice and send it to their warranted repair shop. I've heard nothing but good about them, though the only thing I've heard of sending a Dickinson back for is triggers that are too heavy.
It may be that they replace the entire trigger assembly for you under warranty, something a regular gunsmith couldn't do. Besides, looks like you are like me in that you've got plenty of other iron to shoot while it's away.

I'd like to know how well it's resolved for you after it's over and you get back to shooting it.
Best wishes, SRH
