I wanto build/buy an 870 for home defence and an occasional 3 gun match. While I am sure that you guys have seen just about everything used I would like to know what is the most popular way to set up an 870 for these events. I guess the first thing I need to know is am I waisting my money buying an 870 express with a smooth slug barrel with the rifle sights? What accesories do I need and would I be better of buying a particular model with some of the toys already there like the HD model for instance. Perhaps you guys could post pics of your 3 gun shotguns. Thanks.
