Altho I do not have one in a Handi.. I do have a couple 28's one in a pump and another in a SXS gun. This is one great gauge, one of my favorites!! Kills all out of proportion to its size. I remember reading that more people have shot there first perfect scores on the skeet field with a 28 than all other gauges combined... I tend to believe it!
I KNOW the 28 is up to this task, if you can shoot it well, it will suite you just fine. Not just for preserve birds either mind you!! It maybe lacking for those late season, long shots and heavily featherd birds, but everything else, shoulder, point, lead and shoot and eat good that night...
