I have owned an 835 for 15 years now and it has never let me down. I do not however, own the slug barrel for it. I just use it as a Turkey and Waterfowl gun. If you plan on shooting the big 3 1/2"s, be ready for a big difference in recoil from your 870. Mossbergs are notorious for whomping recoil for some reason. I think it has alot to do with the way they fit most of the time.
