Remington 1100s were great duck guns in the days when lead shot was legal. They've fallen from popularity with the advent of steel shoot in 3" hulls. If you're going to use high density non-toxic shot (expensive compared to steel) 2-3/4" loads, then the 110 is a great choice. Otherwise, as has been mentioned, you'd be happier a gun with a 3" or 3-1/2" chamber for ducks.
