I have the 870 super mag with the 26" barrel. I really like it and i don't really mind the extra 3 or 4inches. I used to use the factory remington super full choke and i shot a few birdsat 40-45 yards with that choke but then i tryed the turglo Gobble stopper choke tubethis year and my patterns tighten up quite a bit. As for adjustable sightsI have never used them. I have turglo Glo bead on the tip of my gun and thats all i have. The farthest turkey i have shot was at 51 yards. But i can see the the plus side of using adjustable sights but i really don't think you need them at all but thats just my thoughts.
