Don't hold your breath ...........
I work PT in a local HS. I too was waiting for a wing and was given the run-around. The woman on the phone from Sig finally admitted there was a problem. She said they have no good planes or wings instock and infact they were looking for a new manufacturer to build them and had no timeframe. I am very disappointed. We had one on the shelf. Sig is taking both back for full credit.
