You left mine out of the poll. You had one method that was similar.
Rip and tear baby. Hand over the top of the slide, thumb pointing toward body, meaty part of hand covering half of the slide, and four fingers on the other side. Then the pistol is pushed forward with firing hand, and pulled back with the other hand.
It's the same thing for reloads, malfunctions, or just charging the pistol.
I honestly think that this is the most effective/efficient way to go.
Now I'll sit back and listen to the old timers tell me about how much faster it is to use the slide release, even though it can cause a failure to feed by being weaker. Also you have to operate a button. There is a verified story about an SF guy in Afghanistan that hit the mag release button accidentally instead of his slide release in combat.
