Just wondering the insight you can provide about these three marks and how they are less than ideal craftsmanship? What are they from? How were they made? How do those answers indicate they are poor quality? Are you aware of the hk QC process and how it works? Why would they allow something to go out of it did not meet their specs?
I guess things are all relative. In my experience, $500 is toward the bottom end of pricing on duty grade handguns. Complaining about three marks that you don't know why they're there or what they're from seems petty. If you had paid $5,000 for a custom STI, you would have high expectations on all fronts. While tiny marks that are inconsequential may still be trivial in that case, I would understand being disappointed in the fit and finish because you don't the money for something polished.
