FWIW I had to return new guns to Springfield, Ruger & Smith & Wesson due to faulty QC. I can remember back to when my agency ordered a batch of new stainless revolvers to replace our aging Model 15s. Some came through with problems so severe that range staff could not fix them and they had to be returned too, so nothing new here. I also purchased my last two new S&Ws from Gander and found them to be both knowledgeable and helpful so I don't want to bash them unnecessarily. I learned, the hard way, to carefully inspect any new gun I purchase.
