Ok, since you've admitted your education is lacking I'll explain it to you.
When I put my finger on the trigger and my other 3 fingers through the factory installed loop, the loop is t-o-o s-m-a-l-l. In order to shoot with a grip that's even close to being comfortable, I've got to put just two fingers through the loop and leave my little finger on the outside of the loop. Otherwise, ALL of my fingers through the loop are squeezed tightly.
So, with the big loop lever, the one you don't like, I hope to be able to shoot more comfortably.
I've watched very few John Wayne movies, and none that I can remember, that has him doing the "twirly thing."
