Demonstration of ideal OPP grip in competition. Notice thumb angled 45 degrees to bore, not straight down. Wrist Straight not cammed. You can see the larger off hand forearm muslecs do most of work enabing Trigger hand to be lose aiding precise trigger contol. This enables the elbows to be highly flexed which absorbs recoil, makes arc of fire shorter and makes field of dot larger. Off hand thumb is virtually in line with bore axis which cuts down muzzle rise. Also much easier to shoot arrond barriers
