They're great shotguns. They don't always cycle 2 3/4" target loads with the factory barrels, but you can put one from a standard 1100 on them and they'll work fine for that. Most came with 30" full choke barrels. I've scored a couple of 3" steel shot barrels with screw in chokes over the years, so I use mine for duck hunting mostly.
Parts seem kind of hard to find right now with Remington gone out of business and back again (I think they have plans to bring the 1100 back though). Then again, there's millions of them out there and the only difference between a magnum and a 2 3/4" gun is the action sleeve, which you'll probably never wear out.
