Has anyone checked the part differences between a standard 590 and the short (1¾") shell compatible 590s?
Is the difference in reliable short shell feeding as simple as swapping the 590 shell elevator for the one in the 590s?

Looking at the OF Mossberg WS, it is a new style lifter, bolt carrier and an "energy absorbing bumper". A $17 OPSol Mini-Clip allows you to shoot the Mini shells, but you cannot alternate loads in the same tube. If the the Mini-Clip is in, it is a 1 3/4" gun only. Pop out the Mini-Clip, and you can shoot the 2 3/4" & 3" loads.

I think it is a little more complicated than that. Read this article to find out more... LINK
