Customer came in yesterday with a Super Blackhawk. Asked me to look it over and see if I saw anything odd about it. Barrel had unscrewed itself, front sight cocked over, enough that the ejector rod would not enter hole in frame. Barrel was loose enough to turn easily with a couple of fingers, didn't see any excessive wear or damage at the forcing cone or anywhere else.....Sent it back to Ruger yesterday, have to wait and see what they have to say about it. I've never encountered such a thing. Makes me appreciate my P&R Smiths!
