Things I liked:I got the 880 a week ago and used about 800 rounds so far. It's very accurate (even with B .B.'s) with the iron sights, which took just a minor adjustment. One of the advantages of the 880 is that you can adjust the power by the number of pumps. I can use 4-7 pumps when shooting outside and 2 pumps in the basement, where I don't want high speed richochetes. At 7 pumps I fired at an old phone book and it buried a B.B. on page 278. Nice power! It holds 50 B.B.'s which are easy to load, so I can shoot for an hour with little effort.
Things I would have changed:The lever action is not difficult, but still the hard plastic of the lever was jamming my hand when it clicked into place after each pump. I solved this by wrapping some leather a couple times around the lever where you grab it (glued it in place). That worked just fine! The only thing I would change is the plastic bolt. It feels flimsy,like it might break, and I wish it was metal. (Of course it may last for years!)
