Regarding the M series, why do they call it a DA trigger?

I am new to steyr handguns, and love my M9 thus far, but I am curious about the trigger system. Clearly it is not a tradional DA or DAO trigger. The trigger wieght is impossibly light and short to be actually drawing the hammer/striker back. This is obviously done during the cycling of the slide, which would make the M series a SA trigger, or something similar.

I hear it described (including by the manufacturer) as a double action trigger, but this can not be the case, at least not in the traditional sense. So what is the explanation?

Racking the slide does not FULLY precock the striker. IIRC it precocks to approx 72%(or there abouts), this is said by Steyr, to not be enough to ignite a round should the sear somehow slip or malfunction. Only by virtue of pulling the trigger rearward to complete the cocking action can a round be fired. Similar to the Glock, but having more precock, hence a better trigger(in my opinion.)
