If it is not on the roster,you might be able to purchase it if it has been converted to single action only. The other option is to find an older 586 for sale in the state and do a PPT,or if you find a dealer with one on consignment,get it. If it were me I would be looking for an older model and get it. It might take some looking,but it would be worth it.
I picked up a nice 686 (my last duty wheel gun) a few months ago in very good shape for $595. Found it on consignment at a local shop.
