Heard more from Cor-Bon today
They received the revolver this morning, and assessed it as totaled. They are replacing it, but salvaging my Hogue grips, cylinder release latch, and sights, in case I wish to mount any of those parts on the S&W 29 they are sending as a replacement.
I have to say, my experience with Cor-Bon customer service, and Ross in particular, has been stellar.
Will update when the replacement arrives.
Note: Still haven't heard back on my email or voicemail to S&W customer service. They usually have a good reputation, so this surprises me. Luckily, in this instance it doesn't really matter because Cor-Bon has stepped up.
