Slight muzzle burr on Ruger MkIII

[Mr.CRC]

Hi:

I have a new Ruger MkIII Hunter pistol. There is one rifle land on the muzzle that is slightly burred. It's barely visible, but apparent under 7x magnification.

Should I be concerned? If so, how can this be fixed? Can a gunsmith lap the lands at the muzzle to make them smooth without damaging the barrel?

Thanks for comments.
