imo expresses are JUNK. wingmasters are great. i have a 500 made probably around 1980 for hunting birds abd use my dads wingmaster with a slug barrel. made around the same time. both are great guns obviously the remington has a nicer feel and is better quality. the mossberg is great for duck hunting becuase im not afraid to beat the crap out of it. i have shot one express and it is a piece of junk. if the guy who owned it agreed. the thing rust like there is no tomorrow. i would buy a mossberg 500 any day. the only remington i would buy is a wingmaster made before 1985
