I used to have a Walther PPK/S that I would sometimes pocket carry. I sold it to a friend of mine, and wished I hadn't. Might have to get one again some day.
Depends what I am wearing and where I am going. Sig 239 40 S&W IWB or Walther PPK/S 380 IWB or OWB or Sig 230 380 ACP in my back pocket or coat pocket.
Usually a kershaw, then a glock backs that up, or maybe the other way around? I haven't ever needed one gun nonetheless two, but it could depend on the field you are in or the circumstances.
