As JG alluded to... the (standard field stocked) Super Nova has no more or less recoil than any other pump shotgun in the same weight range, with the same stock composition and similar LOP and recoil pad.
IMO... If you're looking at the version with the "ComforTech" stock and GR sights, (stock number 20155), this would be the most comfortable shooting (and practical) tactical SN to have, followed by the PG stocked (20160) model... unless you don't like GR sights that is.
