Trigger Pull: Tip Of Finger or Crease In First Joint?

[jeff68]

In the various gun videos I watch, gun tv shows or photos in gun mags, I see almost all pulling the trigger with the index finger's first joint/ crease.

As a young shooter, I was always admonished to use the tip of the index finger as sensitivity was greatest there.

When did that idea go out the window?

One less muscle group to control at the crease. Better in my opinion.
