dent on crown

I just bought this S&W and after I had a couple weeks, I noticed this flaw on the crown. In the photo at about 6 o'clock.



The gun seems to shoot decently, but that flaw is very annoying. How should I have it fixed? Just have them fix it under warranty or pay to have the PC cut a "recessed crown muzzle?" Or have another gunsmith cut a new crown of another kind?

I put an arrow on the picture. It looks like the dent was there before they glass-bead blasted the muzzle and top of the barrel at the factory.
No, the dent does not touch the rifling, but theoretically, the crown is just as important. That dent will create turbulence in the gases as the bullet's base exits the muzzle, potentially upsetting it. That's why people pay big money to have precision and polished crowns on their muzzles. I've seen some evidence that a crown flaw can change the point of impact, but won't necessarily affect accuracy. If the flaw introduces yaw into the bullet, it will either stabilize afterward or tumble.

Honestly, shooting this gun double-action, I doubt I will ever notice an issue. I haven't so far. But I'm disappointed that a brand new gun comes with a careless blemish like this in an area where special attention should be paid in quality control. I want the gun for training, so I will probably not send it in until I'm ready to part with it for a while to have some upgrades done (moonclip and chamfer, overtravel stop, action job, haven't decided what all yet).
