There's nothing magical about it. It's simple mechanical advantage. Most people can generate more power punching the grip through, while holding the slide overhand, than they can generate by trying to pull the slide.
Pulling the slide isolates to the biceps, forearm, and hand muscles.
Punching through involves core muscles, pectoral, and triceps, while still using some muscles of the weak arm and hand. IE it uses more and bigger muscle groups.
Nailed it. It's all about mechanical advantage.
In effect. It really doesn't matter whether you push the gun forward, pull the slide back or do both. In any case, after the slide has reached the rear most point in its travels, it needs to be released to fly forward on its own -- not ridden down.
Personally, I pull my slide back. In our monthly Basic Handgun classes, we have some students who have trouble doing that. But if they push the gun forward, and especially simultaneously pull the slide back, they can manage. We also have them turn their bodies to keep the gun pointed down range and hold the guns closer to their bodies.
