Looks fine on the inside where it matters. Appears it just got stroked a bit much cleaning up the frame. Cosmetic only I'd say. I'd probably file the other side to match if it were mine.
But you can certainly send that photo to Kahr CS and see what they have to say.
A new frame would require another transfer since it's the serialized part but if it's wrong that's the thing to do I reckon.
