Thanks 101,

Would someone have to be pretty strong to hold the slide like that? How much force would it take to prevent it from going back?

It depends on the weapon model, really. We trained on this in the military in hand-to-hand combat exercises (sounds super awesome Navy SEaL-ish, but I assure you it wasn't, it's pretty basic).

We would simulate a close quarters encounter with a combatant armed with a handgun, and we would either get our hand in front of the hammer (if there was one), or try to prevent the slide from moving.

No training is required to do this, and it could happen on accident during a struggle over a firearm if the other guy gets his hands on it tightly enough.
