I love mine, I mainly use it for waterfowl but I shoot the premium 3.5" shells all the time and it has not failed me yet. I have had it for a few years now but I have not shot 2000 rounds but I don't see why it wouldn't. It is about the most rust free gun you can get the stock and reciever are a one piece glass reinforced polymer and the reciever has a steel insert. Very good design and well built. I clean mine about once a year and I beat on it waterfowl hunting.
