I have a sx4 I use for ducks geese etc, and a a300 for turkey. the 300 is heavier I think (not weighed but sure feels like its heavier). Ive never had a single issue with either gun and both are great. I LOVED the 1100 back in the day, but both are light years ahead of it. pick whichever fits best and go shoot. I will say, for me, I bought a browning gold a few years ago an 1. could not hit a thing with it and 2. the safety was in the front of the trigger guard. I never could get that thing off easily. I grew up shooting thousands of rounds thru my 1100 with the safety in the back and thats where my mind and finger went to. just some food for thought. both the guns you have listed have the safety where it should be lol.
