Steve; I had an issue with a Smith 629, and got pretty ticked off at Smith Service....According to them, what I considered a defect in the rifling of the barrel, was a flaw that is common to the machining process that they used for rifling their modern guns. After I cooled down, I just accepted that answer, and have used the gun with no problems, and it is very accurate for what it is. So if, or until something adverse happens, I am going to take them for their word...after all "they" built the gun...not me. Other than that, they were prompt, and explained everything about the issue to me, and I feel that their service was very good...although I wasnt happy at the time with the answer they gave me!!!
