I have an old 870, probably circa early 70's, I'd guess. It's semi-retired at this point, only seeing use when I hunt in a slug gun only area. Smooth as butter, and never a jam. Not once. I've had several of the newer 870's pass through my hands. I don't care for the Express guns. They just don't seem very smooth. Of the newer Wingmaster guns I've had, they all functioned just fine, but didn't feel as smooth as my older one, but it could just be that the older one's had countless thousands of rounds run through it between small game hunting, duck and deer hunting, and a lot of casual trap shooting.
