Smith & Wesson, Colt, Dan Wesson and many others have had QC issues at one time or another. All three also have produced revolvers that some owners will claim are the nost accurate. I've never had a 'bad' Dan Wesson, in fact my favorite one is a Palmer gun which according to internet lore is the one to avoid. I think the DW's proved their accuracy in the Silhoette world.
I understand loyalty to all the brands. My remark to the Python being the most accurate revolver was just that there are other brands that in the right hands will be just as accurate for their owners. I own multiple Smith's and DW's. I've shot Pythons and liked them but can't afford one.
