I spent several years as gun room manager for Sportsman's Warehouse, and Taurus revolvers were the absolute worst guns we sold. I sent back more Taurus revolvers for warranty service than everything else we carried, COMBINED, with The Judge and the single action Gaucho being the absolute worst of the worst. Taurus autos, on the other hand, seemed to be a decent gun, and I can only remember sending back two for service, and one of them was just a screw the customer buggered up trying to remove it.
That said, I've had two Taurus revolvers, a M85 and a M941, and they worked just fine. I still have the 941. If they were all bad, Taurus wouldn't be in the revolver business, obviously, but I had a much larger return rate on them than everything else. The Gaucho was so bad, they got out of the single action business right quick. We only carried them for a very brief period. They were introduced in 2006, I believe, discontinued in 2007 for re-engineering and QC issues, re-introduced, then discontinued for good in 2009.
If you're a big retail chain, such as Sportsman's Warehouse, warranty service is prompt, but if you send it in as an individual or through your friendly neighborhood kitchen table FFL $20 transfer guy, you're going to be waiting awhile.
