I'm looking into getting a Rem. 11-87... I saw where there are different types of 11-87's. I want to use it for waterfowl. I was curious what the difference between the sportsman and the waterfowl edition one are? I know there is a price difference of a $100 or more. I would like to keep the price under 700-750 is that possible?? Currently I'm shooting a mossberg 935 and had enough of it and want to trade it in for an upgrade. Any suggestions would be great!! thank you!
