I have. Years ago I bought 2 older revolvers. One was a model 19-2 which was pretty well used and I was concerned about perhaps excessive cylinder shake and finish wear. It was completely serviceable and showed no real problems aside from the finish wear. Another was a model 28. It too showed finish wear but was completely serviceable. Because I was not sure about any "issues" I sent them in for a check and "service."

Both came back in simply excellent condition. I had them refinished with the flat/mat blue/black finish and the factory gunsmith tightened them and went through and replaced what was needed (if anything was). I was so completely satisfied that I will send my revolvers back to the factory as long as the factory will work on them.
