Mine's 5 1/4 lbs, but it's built on a .410 frame. I'm with Bobby on this one, 5 1/2 lbs in a side by side is about right. Many 28s are built on a 20 frame and will be heavier. Brent's on the right path, except I don't mind a 6.5 lb 12. Over/unders do tend to be heavier in the same gauge because they are more target guns than game guns.
