Larry: The involuntary second pull is pretty well established fact for all STs (see Burrard, Churchill, Gough Thomas et al.). The second pull occurs a microsecond after the first, as the gunner's reflex follows the recoiling trigger. Most modern STs incorporate a slight delay between barrels, during which the involuntary pull occurs. Boss is one of the few that actually use a three-pull system. Burrard's The Modern Shotgun, Volume I addresses this issue in depth.

If DTs are generally better, why is it that the most popular doubles around the world today, O/Us, are almost all STs?
