I have a MK9, like the gun you mentioned, and don't really have an OWB holster for it but use an IWB holster called the Comp-Tac 2 O'clock. This is a very compact appendix carry holster, which I find works well for such a small gun as the MK9. The MK9 is so thin (0.90 inch slide thickness) that wearing it IWB with a holster of thin Kydex is quite feasible without buying a larger pants size. The belt over the gun and holster also helps keep it from tipping outward, which can be a problem in very short barrel guns. The belt loop on the 2 O'clock is offset from the gun so it doesn't add thickness.
