Came across a gunsmith yesterday- he got schooling under a S&W guru. Tuning Smiths and I mean really doing a nice job! He's a good guy and knows what he's doing. You can Google him at Soap Creek Armory. He's going to work on a couple of mine. If you need a tune job, timing, headspacing, etc, he's your man.
Best Regards,
Tom

Just curious....if you only came across him yesterday, how do you know he's such a great guy with Smiths?

I handled a couple he'd tuned, watched him work a while. He's got a good reputation here in SE IA.
