I am not aware of the factory flat trigger changing, and the Sig web store does not specify, leading me to think that it probably would. You can always call Sig to confirm, although I would expect them to strongly encourage you to get the upgrade, regardless of the answer to the question.

This might sound dumb but what advantage does the flat trigger have over a standard curved trigger? I've never had the opportunity to hold---let alone fire---a handgun with a flat trigger.
Flat triggers should improve precision work. I have one installed in an olympic match pistol and I was experimenting with it quite a bit until it was set correctly. It works well with a correct trigger reach AND when the trigger face has an exact 90° position to the barrel axis when the shot is breaking AND when overtravel is adjusted to the bare minimum. I like it but it´s not the wisdom´s last word. The characteristics of the second stage feels differntly to me. more direct, and harder (not heavier) and I ended up with more flyers in the beginning, until I readjusted the weight ratio between the first and the second stage, because I overran the second stage. From what I experienced until now is, it´s a good concept for precise slow fire but do to its complexity it might not be in the favor for rapid fire unless trigger reach and angle can be adjusted. If characteristics flat face trigger would have a benefit in a service type pistol used for rapid fire at short distances is something that can be debated for that reason.

I believe the flat PELT-2 triggers at Gray Guns are made of a tougher steel than the OEM triggers that come with the new guns. Something to do with keeping the price down on new pistols. However, both are probably extremely excellent.
