When I had my XD9SC I carried in a UBG Canute. http://www.ubgholsters.com/iwb.htm
For those of you who carry the XD 9 sc, what holster do you use?
Not an XD owner but for my G27 (similar to XD) I use a Crossbreed. You have endless options.
When I had my XD9SC, I used a CompTac C-Tac which I personally didn't like very much. For OWB, I used a Galco Matrix, which was an excellent yet very inexpensive option. Don't forget that a gun belt is part of the equation.
