From personal use of the Mossberg and basically no other make... I say it has what ever to disable the trigger and hammer during cycling.
I have had to just learn to cycle my trigger finger faster to get rapid fire speeds up near auto loader speeds. I hear there are 2 older models of different brands that from factory would "speed fire" I don't know if it is possible to modify the Mossberg to do so. One may have been a Winchester and the other may have been an Ithica.
