My recent purchase of a new 625-8 (pc 45 acp) had a horrendous burr around the outside edge of the barrel forcing cone. It looks like it was cut and squared with a cutter, and someone failed to remove the burr.
My 629-6 Stealth Hunter had the exact same issue, in fact it still does. It also has many other issues that a $1600+ gun shouldn't have.
The cylinder to barrel gap is a loose .008". That's quite a bit bigger than it oughta be on a hand-fitted revolver, and it emits HUGE flash out the sides when shooting full power .44 magnum loads.
The "trigger stop" is a joke. It is not adjustable, it is simply a roll pin that allows considerable rearward movement after the trigger breaks. I guess it's adjustable in that you could file it down so it would be even more useless, but normally trigger stops are supposed to limit the rearward travel of the trigger, and this one doesn't do that correctly. The one on my Les Baer 1911 is an adjustable one (allen screw) that allows me to adjust it so there is no detectable rearward movement of the trigger after the trigger break. That's how it should be.
The back side of the cylinder release has edges so sharp that it has gouged the side of the frame from movement. If they had de-burred it or at least knocked off the edges, it wouldn't have damaged the frame.
The machining of the chambers in the cylinder is rough, like they were cut with a worn out cutter.
It has that "drift adjustable" front sight in a dovetail, but with an adjustable rear sight, who needs a drift adjustable front one? And when I asked S&W if they have alternative front sights for it or if they know who does, the answer was that they don't, and they referred me to HiViz who also doesn't have anything that fits it.
This is all pretty crappy for a revolver with MSRP of $1619. I really enjoy the gun now, (after we did a trigger job on it), but if I had known then what I know now, I would not have bought it, and I will not be fooled by S&W marketing again.
