I am considering buying a Remmington 870 (20gage) for Pheasant and Grouse. I love the Wingmaster, but for me its less about "looks" and more about performing in the field. I know a lot of people like the O/U's and I still am considering that myself, but wanted to hear from you who hunt with the 870 Express. How does it perform in the field? Happy with it? Etc.?
