I've noticed that most of the top shooters seem to hold the forestock with their forefinger on the other side to the other three fingers. Naturally when I hold the gun I hold it with all four fingers on one side with my thumb on the other but I thought I'd give the other grip a go at the weekend. I don't know if it made me shoot better but it did seem to make me hold the gun further away from the trigger which actually made my swing a bit smoother. Firstly, how many people hold the gun like this and secondly what is the main reason for it?
