Thank you very much - the used gun I am looking at is the Benelli Sport, the link had good info but it was about the Sport II. The Sport I am looking at is a little different so I would guess the Sport must have been the first model and the Sport II is a later vintage. The Sport is in real good shape but before I buy it I would like to hear some reviews on it, it appears to be very light which is good but the vent rib rattles and is made of some type of fiber - kinds like the current ultra light. Does anyone have information about the Sport?
