Re: A recent poster's comment. The Model 21 Duck or any other Model 21 is not suitable for steel shot. The Model 21 3" guns are not made with dedicated thick barrels, unlike the factory 3" Model 12 which does have dedicated extra thick barrel. The Model 21 3" chambered gun and the identical Duck Model seldom weighs any more than 7 3/4 pounds in solid rib 30" persuasion. Oddly, it is not unpleasant to shoot with heavy loads, but probably because of the targets we normally shoot with it which take our minds off of recoil. By the way, I'll open those steel Federal shells first chance I get.
