I shot my 21 at ducks last week. It has 30 inch barrels and is stocked to my requirements. We shot the morning flight of woodies and I found the gun a bit slow compaired to my 390. The price of the bismuth shells is a bit pushy. I had fun, would have done better in a blind with the 21 but not many ducks in LA with temps in the 80's. For rough hunting I think the black plastic makes a lot of sense.
