Ggp quality control is lacking - Grey Ghost Precision Sig P320 Version 1 Slide

So, this is in no way a slam on optics planet, they offered RMA to make it right, but ultimately I didn’t feel like waiting 2 weeks for turnaround because functionally nothing wrong, just not what I ordered. Ordered a version 1 slide, not version 2. Checked order...version 1, box was marked version 1, got version 2 without window cuts. GGP put wrong product in box. Was so laser focused on putting parts kit in, I didn’t notice right away. Since it was same price, and functionally same, and still a nice looking slide, I guess I will live with it, but wont ever purchase a GGP product again. No attention to detail...
