I'd check out www.comp-tac.com
I've ordered all my holsters from them. I use the Comp-Tac Minotaur MTAC IWB holster. The nice thing about their holsters is that the kydex bodies are interchangeable for different guns. So you can have one leather backing and spare kydex bodies for every CCW gun you have.
I usually pick up my belts from the local LEO dealer. Make sure it's a strong duty style belt with good reinforcement. If you're a 30", I'd get a 32"-34" belt to accommodate gun and holster.
