Default Oil Pump Rotor Problem?

When my car finally gets warm my oil pressure drops to around 6 psi at idle (850 rpm). I made sure there were no leaks and that everything is installed properly to no avail.

I ended up pulling my oil pump and saw that the rotors look strange. I have attached pictures of the rotors. I was curious if this is what a new pump should look like or if some damage may have occurred(looks pitted but might just me machining). The motor and pump only have about 5 miles of light driving and 30 minutes of idle on jack stand.

There does not appear to be any significant damage to the rotors, however it's clear that the pump has ingested debris of some sort. When it comes to rebuilding engines, cleanliness is godliness. Good luck.
