I'm trying to understand the quandary. Isn't swapping out barrels on an 1100 pretty easy? I know that swapping barrels on an 870 is danged near idiot proof - it's a simple matter of unscrewing the knob, pulling off the barrel, seating in the new barrel, and screwing the knob back on. Of course that's a pump gun - an auto shotgun might be a bit different though, and I've personally never done it.
In any case, finding a slug barrel for an 1100 is as simple as doing a Google search on "1100 slug barrel" - all kinds of options pop up.
With that said, it's never a bad idea to pick up another gun, and an 870 slug gun would be a decent addition to the family.
