I sent mine in. Turn around was about a week from the day I shipped it until it came back. Before the upgrade I was pretty ambivalent about the trigger. I definitely shot other pistols better. I had planned on selling it once I got it back.
However, when I got it back I took it to the range just to test fire it and make sure there weren't any problems since the upgrade. I was actually shocked how much better it shot with the new trigger. I think Sig turned it into my best shooting pistol. So I decided to keep it.
