I'm trying to decide on the optimal location of my index finger on the trigger of my DA/SA Sig pistol, and would like to get the thoughts of more experienced shooters. The SA pull is very smooth and comfortable using the pad of my finger. I can also use the pad of my finger on the DA pull but get better leverage using the distal joint. It's my impression that you should maintain a consistent position on the trigger. The problem is that if I consistently use the pad of my finger I get fatigued after a number of DA pulls. But if I use the distal joint it quickly gets bruised. Maybe I should just use gloves.
