Except for my trash first gun, a Taurus 83 I bought in 1977, about 3 days after I turned 21, my revolver issues have been pretty minor, and most of them fixable by myself in a few minutes:
The Taurus had so many issues, they should have replaced it, but even though the barrel was only partially rifled, they insisted it was "fine", and refused to fix it. Sorry, I prefer to be able to shoot my guns more than six times without having to pound the lead out with a brass screwdriver.
1. Used Dan Wesson 15-2 had light primer hits. Previous owner had shortened the mainspring and replacing it had the gun at 100%. I fired that gun at least 5000 times after I fixed it, with zero issues.
2. Used Colt Python, blue, 6", the hand broke about a month and maybe 100 rounds after I bought it. A local GS fixed it. That was the most I ever spent fixing a revolver.
3. Dan Wesson 15-2 (Different one than above) Too long a grip screw, installed by me, made the gun unsafe. About 30 seconds with a grinding wheel fixed it.
4. Dan Wesson 15-2 (Another one!) The most worn looking one I ever had. Broken hand spring. I replaced it, and the gun was back up. I carried it at work for 3 years+ and shot it a couple of thousand times without any issues.
5. S&W Model 19, 4" LNIB. Trigger wouldn't return to firing position on the third shot after buying the gun used at a local gunshop. They fixed it for free while I waited. I don't remember if it was something actually broken, or it was gummed up inside from sitting in the box for about 15 years.
That's the total of my revolver issues.
My list of woes with both new and used semiautos would be a dozen pages long. I lost respect for several companies after dealing with warranty issues that weren't ever resolved, and gained respect, and they got future business, from companies that fixed the problems that came out of the box. One even replaced the gun, and tossed in a couple of free mags with it.
