You are on the right track, if you are looking for a light gun you have to start with light barrels.

My Ithaca SKB M-100 20b 25" has the older Roto-Forged mono-bloc barrels, they weigh 2 pounds 5.5 ounces without the forend. They are chrome lined and factory chambered for 3" cartridges.

And my Ithaca SKB M-200 20b 25" barrels weigh 2 pounds 8 ounces without the forend. They are also chrome lined and have 3" chambers.

BTW, the lightest set of 20 bore barrels that I have are on my 1933 Arthur Howell 28" boxlock ejector, they weigh 2 pounds 5 ounces. But these are dovetail lump construction with 2 1/2" chambers. This one weighs 5 pounds 2 ounces all up.
