I have bought 4 new S&W since 2011, none had canted barrels but did have other problems.
Model 63 - terrible lead spitting and huge gap between cyl and forcing cone. - S&W replaced the barrel in less than 2 weeks and is now an excellent shooter.
442 no lock - Perfect
Governor - Perfect
627 Pro - perfect in appearance and quite accurate.
Sometimes when releasing the trigger it would not reset properly so on the next shot the cylinder would rotate but not cock the hammer so it would not fire thereby skipping a round. This one is back at S&W now.
Obviously not a big sampling but, both of my failures have been with Stainless guns.
