Actually you see it all the time for all manner of defects. Some folks seem to think Smith is the only place qualified to work on a revolver.
Personally, Smith would be the last place I would send a gun to be repaired unless it was a blatant warranty issue that required the gun be replaced in whole.
If they could not get it out the door originally in proper order, what would ever give you confidence they can fix the issue with any level of competency?
Given the constant flow of posts here about current QC at the factory you can bet the issue runs all the way from the top of the company to the shipping clerks. It is culture. They either have a culture that produces quality or they do not.
Find a local gunsmith that deals in revolvers and you will most likely be much happier.
I have two gunsmiths I work with. One for rifles and handguns and another who specializes in double barrel shotguns. I am blessed in the fact that the shotgun guy is local but nationally recognized for his quality and the other guy has just never sent me back a problem, only solutions.
