3a. Transition timing: you pull off the target before the gun is finished shooting it, or shoot before the gun has arrived on target
3b. Transition damping: your transition wasn't 'critically damped', and you overshoot the target.
4a. Sight alignment: sights misaligned
4b. Sight placement: sights aligned but aimed wrong (usually looking at the wrong place on the target)
In this drill, you've got the possibility of a combination of causes. For me, when I'm shooting a transitions drill and pushing speed, my dropped points are usually due to 3a&b.
About the 1911: I'm not surprised. Did you shoot the Glock first? When you switch guns, that can introduce issues. Your brain thinks it's shooting a Glock, when you have a 1911 in your hands. It can take some time and ammo to make the switch. Some people can juggle multiple gun types, and others have more difficulty.
