My last purchase of a new revolver was in 2003, a 325PD with a hole in the left side. I fixed it. Many years later, S&W replaced a problem revolver with a 22-4 1917 reproduction made in 2007. It, too, had a hole in the side which was promptly fixed.
Other than that, I haven't gotten my hands on a new revolver since 1995, although my 1983 Model 37 looked like new when I bought it in the 21st century, except for the few rounds I fired through it to check POI.
Unless I change residence and buy a Casull in .22LR, I'll probably never buy another new revolver.
