Which part or your trigger finger do you use and why?

Use whatever it takes to get the trigger to come straight back. Every gun is different.

Definitely depends on the gun. For punching paper and shooting tight groups probably best to stick with one gun.

I feel if I ever need to use a gun "for real" odds are I'd have to use whatever is available at the moment of need so I like to shoot a variety of guns. I have a "natural" trigger placement that usually works well enough that varies what part of the finger is on the trigger depending on the grip size and trigger reach. But I've a few guns where I've got to consciously adjust the placement if I need to hit small targets, otherwise the pull is not as straight as it could/should be.

I use the middle of the distal phalange pad on revolvers, pistols, and rifles as this allows me to press the trigger straight to the rear on 1911s and have a more straight and consistent trigger stroke on the other guns. I tried using the "power crease" to pull the trigger on my revolvers and my accuracy and scores in competition went downhill. If you use the "power crease" to shoot a revolver, the arc between the proximal-middle phalange joint and the trigger is much shorter causing the gun to move to the left on trigger take up and to the right on firing and follow through. I also can't use the power crease when shooting snub nose revolvers. I have long fingers and large thin hands and the tip of my trigger finger would touch my left hand as the gun went off.

If you can't work the trigger of your revolver with the pad, your fingers may be too weak, your revolver's trigger pull too heavy, or both.

If you have different sized hands your reach will be different as well. Not every hand/gun combo will be the same.
