The above is the typical problem with 20/28ga 2 barrel sets: almost always heavier with the 28ga barrels. Not a bad thing for targets, but if you're looking for a lighter field gun, you're going the wrong way. And that is indeed what happens when you put 28ga barrels on a 20ga frame. I had the same situation with a Citori Lightning Feather combo set. That's also why the Parker Repro 16/20 2-barrel sets are LIGHTER with the 16ga barrels: they're mated to a 20ga frame. But that's atypical.
