I can't stay out of this.

In the beginning LOP was measured from a fixed trigger to three points on the end of a straight stock. Then we got pistol grips and single triggers. We now have movable triggers.

Now the argument starts.

I say that a movable trigger allows for different finger lengths
and has nothing to do with LOP.

I say that LOP varies with the weight and balance of the gun and the use of that gun.
