There are reasons why a 28ga may weigh more than a 20ga when comparing guns that are identical other than gauge. I own several 20ga guns. 101 O/U, Grulla SxS side lock, 37 Ithaca, Beretta auto-loader, 1100 etc. I have a Citori 28ga 28" bbls and a Beretta Silver Pigeon S 28ga w/26" bbls. The Silver Pigeon is built on a true 28ga frame. I am getting too fat an old to chase chuckar, but when I did, I liked the 20ga repeaters. I just had more confidence with a 20. Having said too much already, I've been hunting pheasants in North and South Dakota for a long long time and I think the 28ga is impressive. I shoot a 28 80% of the time. It is efficent. There's more steel in a 28ga than a 20ga all other things being equal, barrel length, frame etc. The wood may very in weight but not much. Often times, the 28s are built on 20 gauge frames.
