Glock basically built it's reputation on providing the worst realistically possible triggers. Having Glock OE develop your trigger for performance is like having your wife pick out a birthday present for your GF.
Looks like a flat faced trigger with a little bit of a forward angle at the bottom like a lot of aftermarket flat trigger shoes. The "bird's beak" looks to be profiled a little differently and looks like a different trigger spring setup. Trigger bar looks to be driven from the bottom of the trigger bar instead of at the top by the cruciform by the looks of the photo, but it's hard to tell.
