I routinely shoot with a friend who has a 32ga. 686 Beretta; not common, but they did make them. He sourced the gun through Cole's & has another set of bbl's for it as well. I want to say he purchased it about six, possibly seven years ago. I think they special ordered it for him, but don't recall the exact details. I can ask him and post, if anyone is interested.
Also, FWIW most any hardware store in Uruguay will have both 32ga. & 24ga. ammunition on their shelves. Apparently a lot of single shots were sold there to both farmers and the locals chambered for those two rounds. One never sees the guns, but I'm told they are fairly common.
