I haven't hunted with a SP10 or Ithaca Mag 10 but I have hunted geese considerably with 2 BPS-10 gauges, one with a 24" barrel owned by my father in law and now with my own 28" barreled BPS 10 gauge. I know the exact reservation you are having thinking about wing shooting with that stubby 24 barrel but as mentioned above the longer receiver and overall weight more than make up for the lack in length. I had the same thoughts when my father in law offered to let me borrow his gun before I bit off and purchased my own. The short barrel did not negatively affect the swing characteristics like I was expecting it to and the long range performance is no different than the 28" barrel I now shoot on my own gun. These are kind of weird statements coming from me because I am a fan of long barrels, my skeet gun has 30 inch barrels, my go to hunting gun is a 12 gauge BPS with a 30 inch barrel that I swap to a 32" full choke barrel when playing long range trap games. My model 12 is also a 30" barrel. Obviously I am a fan of long barrels but in this particular scenario (weight and overall length of the SP10) I don't think there is anything to be gained by replacing the 24" barrel with a longer one. You will love the enhanced performance of the 10 gauge on geese if your experience turns out anything like mine.
