I have been using an 870(Wingmaster and Express) for the past 35 years. It has never failed me. They also fieldstrip very easily in case there is a jam. It was in a boat with 3 semi-autos a few years back that was sunk during a storm. We managed to retreive everything and with all that slewgoo covering everything, my 870 was the only one that still worked......good enough for me
