People have different size hands and fingers so what works for one may not work for others.

When shooting you'll notice you can adjust windage my putting more or putting less finger in the trigger guard.

As you shoot your pistols (assuming right handed) and your group is to the right, side your trigger finger to the left a tad. If your shooting to the left, put more of your trigger finger into the trigger guard.

To see how this works, dry fire a pistol with a laser sight. Slide your finger back and forth on the trigger watching what it does to the red dot as the hammer falls.
