A 4oz pull that moves a trigger a small faction of an inch can release a thousand foot pounds of energy.

Yes, but we're talking about a system in which thousands of 4oz pulls are happening in different directions at any given moment. You model doesn't only have to explain why a particular pull triggered it, but also why the other thousand didn't.

Throwing a cocked handgun into the dryer is different than a leaf falling on it.
