Honestly, Your 2 3/4 in. 1100 will drop geese! BUT if your hunting with guys using 3 1/2 mags your going to be at serious disadvantage! You will not have near the range or near the amount of Shot! But like i said your 1100 will do the trick, but for this boy, i want all the advantages i can get! My grandfather also had and 1100 and it had a 30 in. barrel and was full choke! I can tell you this, My benelli defineatly aint my grandpa's Gun! I gotta oil that thing and clean it after each use and if i dont, i get rust and it doesnt cycle right! Not my benelli, It doesnt rust and its a breeze to clean! I would never spend money on any other shotgun, besides a benelli or Berreta! I do like remingtons but i dont think they are worth as much as what they are going for these days, with the exception of the 870 and the 1187 waterfowl!
