If you have a Parker Repro 20ga that weighs just over 6#, you may have found the lightweight champ. (The one I own currently--also a SST 26" Repro--checks in at 6/10 on my postal scale.) Olin Kodensha did a very nice job of keeping the weight down on the 28ga Repros, and even the 12ga Repros if you compare them to classic American 12ga sxs. But not so good on the 20ga Repros. And although I'm strongly biased in the direction of sxs vs OU, I've handled several 20ga Superposed Superlights that have tempted me to try one out on woods birds.
