You have to remember not all 870's are created the same. The "Express" models are constructed far more cheaply, with a much lesser degree of detail applied to fit and finish. The Police and Wingmaster guns are fitted and finished much better, and they contain all metal trigger groups, not plastic ones. The "Express" models are cheap, budget guns, where as the Wingmaster and Police Models are top of the line pump actions. Hence the large difference in price between the two.
