For years (and years and years) I shot with strong arm straight, support arm bent in that Methusalah era push/pull grip. Within the last few years I've adopted elbows moderately to slightly bent and rotated upward which creates a torquing vise on the pistol. Kinda weird at first, but far less fatiguing or jarring now that I have fully adapted to the switch. Pistol seems to drop back on target better for me.
