Walther did not respond to my last email. I gave up on it. CS has been horrible overall. A fourth return is ridiculous. My wife handled it and wants to shoot it before I dump it. I will let her try it out. Walther is no longer on any of my wish lists. I could see buying a PPQ or PPS again someday, but as of right now, I am pretty unhappy with the company.
Given that you already had issues with emails being ignored I'm not sure why you'd expect different now. If you're serious either call or let it go at this point. You have a pistol that seems to function fine, it's just not the exact color you wanted. While it might be grating, maybe it's time to look at the forest rather than the trees?
