My older 870 Wingmaster went to a reservation in Montana after the divorce. I loved that gun. I replaced it with an 870 Express. I do not love this gun. It seems much lighter duty and not as tight. Jambs occasionally. I ran across an article that describes upgrading some parts to "police grade" standards. Magazine spring, sear spring, Police Trigger Group, Carrier Dog Spring and a Non-MIM Extractor. Parts are under $100 and I can do the job in about an hour. Has anyone else made these mods and was it worth it?
