My 2 cents: I'd bet 90+% of buyers never inspect their guns that close. And many of the rest of us don't care.
I've ordered a S&W Model 29. Maybe someday the distributor will ship it...looks like they are trying for the long side of their promised 3-7 business days. If it doesn't look like someone ran over it with a truck, I'll accept it.
Then I'll tighten any screws that need it and go shoot it. If it shoots well and the finish is good, I'll be happy. I paid less than I did for my Ruger Alaskan, that shoots great but looks like it was finished by dragging it behind a truck.
If it shoots poorly or the finish sucks, I'll ship it to S&W for fixing. I'm confident they will make it right. Then I'll shoot it until I'm too old to hold a gun. Then my kids will fight over it.
My Ruger Alaskan shoots great. Looks horrible, but shoots great. The first time I shot it, the rear sight nearly fell off. The gun shop where I got my CCW license and that did the transfer said to bring it by. A dab of red locktite, and now it just shoots and shoots.
I honestly don't care if the barrel is slightly canted if it shoots well. For $750, I don't expect a gun made by the Elves in Rivendell. I do expect, and am very confident I will find, that S&W will do whatever it takes to deliver a good shooting gun that I will enjoy for the rest of my life.
I don't know if my 686+ has a canted barrel. It shoots well. The set strain screw backed out almost all the way when shooting, so I cleaned it, applied a bit of blue locktite, and screwed it all the way in. From time to time, when cleaning, I'll check it isn't backing out.
My 60LS shoots darn well for a 2" snubbie. I haven't examined its barrel, but it carries and shoots well.
I'm happy. Happier than I would be if I had to pay 30% more for the gun...
