Situation resolved. Buyer sent the gun back, dealer had his gunsmith repair it on his dime.

Not sure why it took so long to resolve, but that's a good outcome IMO. And I think most of us would prefer to do business with dealers who are in that category. No reason we should not discuss, openly, how the various dealers do business. They go above and beyond, good for them--and if, as a result, they get more business, I'd say they deserve it. Pretty much holds true whether you're buying cars, having a contractor do work for you, buying guns, whatever. Those in business should know that positive feedback brings them more business. Negative feedback is likely to lose them business. We've discussed dealers on here forever, and it's good to know which of us has had positive experiences with which dealers.
