I'd love to comment here because I'm a competitive shooter.
There is absolutely no EXACT place on a finger to pull the trigger. It has tons to do with moving the trigger straight back and depends on finger size, trigger placement, grip size,shape, angle etc.... Some it falls on the tip, some further in, some past the first joint, some in the joint. Wherever it falls so that its natural and you can pull straight back.
As to sympathy, really the only one to move is the trigger finger and thumb. The rest should not be moving or wanting to if done correctly.
The best way I can relate trigger pull is more of a press. Straight to the rear. And smooth. And smooth can be(for lack of a better way to say it) smooth, smooooth, smooooooooth, smooooooooooooooooth. Doesn't matter if its fast or slow if its done right. But you certainly have to have good follow through and in MZ its especially critical, just like in air rifle.
Grip pressure is such that I see just a bit of white knuckle in the trigger hand.
Its hard to convince folks that it may fall in different places for each person. But thats the way it is. I also say stay clear of the trigger guard and dont' "drag wood" as best you can, but dont' contort your hand or finger in the process. The contortions are worse than the dragging.
