The reset point on most (box stock) Glocks I've fired is about halfway in the trigger pull, so you never let the trigger go back to full extension if you are firing multiple rounds. You kind of rock the trigger back and forth right at the reset point to fire fast and accurately. It's hard enough to do right with a 5.5 pound trigger, I could only imagine a 12+ trigger, it'd be almost impossible to be fast and accurate.
