The sear is different between them, but also the blade is red and it has a lighter spring. I dont believe the differences(other than the red color) will be anything you could tell from a picture though. Believe it is more just the angle of the sear that is different.
Maybe somebody will have a picture of one of each.
Heres a close-up video of a standard accutrigger though, if you just wanted to see how it works.
