Galco Ankle Glove or Desantis Die Hard. I have both, one for a PPK and one for a 9 Shield and they're great. Not the best place to carry I know, but if one has to dress "neat" and can't get used to a IWB tuckable (I'm still try'n) then these two are tough to beat. Get comfortable with them and you'll have what you need if and when you need it.
