I am surprised nobody mentioned Frank Glenn for the job. He is one of the most competent gunsmiths left. As long as he is working, I wouldn't even think of anywhere else.

You would've had to ship the gun to Arizona, but you would have had that model 28 back in your hands within two weeks I bet, just like new. A friendly FFL would cut shipping cost down substantially too.

He did some repairs on my 629 and it was literally a 6 business day turnaround from PA to AZ and back. He is also probably the last 'master' Colt smith still practicing.

Good luck with S&W. I hope they finally put this issue to rest.
