Yes, I also learned that in my dry fire practice.
However, the grip in picture #1 forces me to have only that front part of my finger on the trigger. The supposed correct amount and part of the finger.
Whereas the second picture I can maul the thing all the way to the second knuckle. Because of this grip, I've noticed the red dot doesn't move as much to the right when I pull it in double action. It's so uncomfortable though I don't know if I can repeat it and or have the desire to continue to do it.
After watching videos, I thought I fully vetted two years ago, picture #1 is definitely bio-mechanically the correct form. I have more of my right hand against the grip and frame as my trigger finger isn't bent outward to make sure I don't place too much finger on the trigger.
I now totally get the desire to have the option of changing out the back part of the grip to something thicker or thinner.
Pulling the trigger from between the first and second joint is very bad.
