Unless you had DETAIL STRIPPED the gun, the smith in unlikely to have even messed with the pins in the frame... as that's not necessary in reassembly.
How far was it disassembled?
If you had detail stripped it, hard telling what happened, and what he might have done.
(How well-regarded is this gunsmith in your community?)
You may have to send it back to Ruger and let them worry about it. They're pretty good about solving problems, even when its not their fault.
