Sounds like you're looking for a 3" capable gun. The Stoger has gotten good reviews, but my experience with it on a rainy day was that it makes a fantastic straight pull bolt action. Could have been my hunting partner that day didn't degrease it from the original packing grease or break it in properly, I didn't ask, just chuckled as he kept offerring to trade it to me for the old mossberg pump I loaned him. Weatherby used to make great shotguns, but they moved there plant so I won't guarantee satisfaction.
Mossberg makes a semi that is fantastic for the price, but like I said earlier the Browning A5 magnum is the standard against which all modern semi auto duck guns compete, find one used in good condition, buy it and don't look back.
