Check this out. I bought a MP3 holder at Target over in the CD and video section. I am using it as a belt holster for my Kel Tec 3AT. The 3AT just does fit without a half a millimeter to spare. The silvery vinyl is placed just right to run along where the slide is. The silver gives it a typical electronic device holder look. No one has paid any mind to it at all. If asked I will just say; "Oh that's my PDA for my work." I have quicker draw than front pocket carry and I can draw while seated.
