When you chamber the first round the trigger goes into AS mode and then the following trigger pulls are in SA. How does the gun know its the first round? Is there some kind of mechanism that detects when the magazine is removed and then resets to AS mode when the slide is charged? If you fired all but the last round and then removed the mag and reloaded it, after firing the last round from the first mag would the gun revert to AS mode for the first round of the new mag?

little itty bitty german elves!
Ok, that added nothing to this post.. but it is funny.
There are 3 modes, DA, AS and SA.
AS is the result of racking the slide and releasing the trigger fully forward, a long not heavy pull.
DA is the result of decocking AS, a long and heavy pull.
SA is the result of a racked slide and a trigger let forward only to the reset point, a short and light pull.
Check out this you tube post. It does a very good job of showing not just explaining the modes.

I understand the three types of trigger modes, my question is how does the gun know that the slide is being racked for the first time and therefore should be in AS mode as opposed to being cycled because a round was fired and therefore be in SA mode.

The gun "Knows" because if you are smart you don't have your finger on the trigger when racking the slide for the first time!
Whereas after you've shot, the trigger is still pulled back when the slide cycles.

Try here for he technical reason. These guys will help you. I know it has to do with stiker position, but not exactly what about it. I would defer to their expertise.
