I would advise you to spend a bit of time shooting it from a benchrest to see if the sights will zero properly.
BTW, in benchrest shooting it's best to rest your hands on a sandbag, this will allow you to nearly duplicate your recoil management when shooting offhand. In addition, any revolver with a one piece barrel should always be shot with the barrel free of any contact with a support, supporting the barrel will impede it's "ring" and just destroy group size. The only exception to this rule are the 22 caliber revolvers, the barrel is so massive in relation to the power of the caliber that it's basically inert.
If you can get the sights to zero properly, there isn't any point in sending it in, S&W will only say it's within specification and send it back to you. As for the appearance, it's a HANDGUN, not some work of Art. It's meant to fire bullets accuratey, not become some object that you spend all your time looking at.
Yeah, I find this quest for perfection a bit baffling at times. However, I suspect that somewhere out there someone is underneath their automobile waxing the exhaust system because they ran through a puddle and if they found the muffler cocked by 1/2 a degree they'd probably want to return the whole car. Bottomline, if it bother you that much, don't look at it, just go out and shoot the gun.
