Plenty of great IWB holsters out there. MTAC, Raven, Comp-Tac, Sidearmor, Bladetech, Pitbull, Desantis, Alessi, Milt Sparks.
Many of us have a "holster box" full of holsters bought, tried on, and never used again due to numerous reasons. I think holsters are a very personal preference. Sometimes one body shape works for one, may not work for another. Some like kydex, some leather, some a hybrid. My best suggestion is to give one or a few a try and see what works best. You can always sell them for close to full value depending on condition. Congrats on the Corssbreed....they make awesome stuff.
