Yeah, didn't see all of those problems with mine either. I must have one of the newer ones because mine doesn't have the fly either which is fine for me because I am using a simple single trigger. Seems like the frizzen spring issue should be a easy fix with a simple phone call, but I agree that never should have left the shop with that issue.
I see what you mean about the cock offset, but hasn't caused any issues on my gun I guess. Mine doesn't look quite far off as yours. All I know it is the most correct Tulle lock on the market today, and mine works great so far. Admittedly my impression is based on a whopping test sample of 1.
I welcome any new locks on the market, seems like we are getting an embarrassment of riches the last couple years i.e. Laubach, Kibler, Track. Hopefully there will be more.
