I agree it's not a premium crown.
I'd suggest you take it to the range & shoot some moderately loaded JHPs, to see how it groups, & then look at the crown afterwards.
If it groups poorly &/or still has those burrs on it you can send it back to S&W or have someone locally run a chamfer tool over it's crown to clean it up.
Shouldn't take much but I agree they should be doing a better job. I've had to clean up a couple of my own.
