Simplify this debate.
For right-handers...
Left-handers adjust accordingly...
If you "grab too much trigger", the barrel will
tend to pull to the "right" and rise a little...
If you "press too little trigger", (Way out on the finger tip.) you will
tend to push the barrel to the "left" and possibly a little down...
It has been said, earlier in this thread, that people have different length and sizes of hands and fingers...
it is precisely for this reason that the
"teaching tool" of using the center of the first finger-pad is used in training!
If you cannot "reach" the trigger with your finger pad without keeping a pencil sized space between your gun and the base of the trigger finger...
YOUR GUN DOESN'T FIT YOUR HAND!
The Bottom Line is;
IF you can "press" the trigger in
any manner that will cause it to travel
consistantly straight back, to the release point...
Then,
it doesn't make a particle of difference how the hell you hold the trigger...
"But, those who practice these methods
Tried and true...
Will be more consistant,
In outshooting you..."
Good form, old boy, good form!
