My choice would be bitone with night sights. The XML is handy to have if this will double as your nightstand gun. Otherwise, don't bother with it. It doesn't make much sense to try to carry it concealed, because it will increase the bulk (forget about IWB).
The strongest point of the subcompact is its size, adding grip extensions and flashlights just negate that advantage, all IMHO of course.
