Chatting with Lendringser today he brought up some good, if somewhat killjoy, points. Will a saboted round have enough spin to stabilize out of a pistol? For defense use, you gotta worry about the discarded sabot bits. They'll definitely put an eye out inside 7 yards. Just some points that may or may not have already been considered...
