I am glad you asked this question and hope you get some real answers. I also have an LCP and, while pocket carry is quite comfortable with jeans on, I was thinking about an IWB for those times when I need to dress up. While I do not normally like clip holsters, because they tend to move around too much, I think one might be okay for a pistol that is this small. Of the two that you have found so far, I like the FIST the best but the Desantis might do. The Desantis probably wont hold its shape for reholstering which may or may not be a concern for you.
