Ok, just realized you're looking for a particular type of ammo, lol. *smacks forehead* Never heard of Critical Defense, maybe if I knew what was different about it, that would help my researh lol. In any case, wal-mart has a pretty big selection of .40 (at least in my neck of the woods), including hollow point "law enforcement" rounds, all s&w.
