Hmmm must have misunderstood Dave's explanation.
I shoot it both ways Morgan, and i usually leave the rifle sights on it for most of the year. I bust skeet with a 26 in.vent rib OR 20 inch barrel with rifle sights. For deer I leave the extended tube off.. just to save the weight and my sling swivel mounts on the magazine cap.. but for defensive stuff.. I forgo the sling and increase the capacity.
