New DW Valor has significant peening on slide -- How normal is this?

[SiegeX]

I've put roughly 400 rounds through my month-old Valor and I noticed that both the slide stop and takedown notches show sign of peening, particularly the former. Fortunately, I don't see much of any wear on the slidestop lever as you can see. This is my first 1911 so I have nothing to compare it against.

Here are my questions:

1. Did I get a lemon or is this normal for Valor's?
2. Should I send it back to DW for warranty repair?
3. Should I be concerned about safety and/or functioning issues?
