Sig P-series used to be world renown for quality, function/reliability, fit and finish. They are also far from cheap often called the Cadillac or BMW (use whatever car analogy you like) of firearms. How would you like it if your brand new P-series looked like the pics in this thread?

Yes, it is cosmetic and the pistol functional, but so what? You pay a premium for a Sig. Sig saw pictures and called this "normal" wear. When asked why previous generations don't "break in" like they responded that they couldn't comment.
I own several Sigs, and many pistols tighter than a Sig without looking like that. "Normal"? If that it is "normal" it will not be normal for me to plunk down my $ on one. Too bad, because a P229 was on the short list.
ETA:
Here are some shots from a brand new P220 SS ELITE (i.e. NOT cheap):
