I ran this same question a month or so ago and it seemed the majority suggested the Crossbreed supertuck. Not wanting to end up with 10 different holsters for my xd9 service I tried it and have been very happy. My wife told me that if she ever found out that I was carrying when she was around she would throw it in the trash. Well I have been carrying for a month now and she has not ever noticed...so good comfortable concealment. Next I want to get an xd9sc and it will fit right in it.
I would suggest taking a look at our Maverick Defender:
Our Maverick Defender has been copied by other manufacturers. It's a very versatile holster, in that it allows you to carry from the small of the back area around to a crossdraw with its adjustable cant. It carries the XDSC exceptionally well.
Crossbreed Supertuck, they offer a two week trial period, lifetime guarantee and a multitude of fitting options for clips and attachments, adjustable and incredibly great people to deal with. I have had many many holsters and for IWB there is nothing better IMHO. Priced right and quick shipping too.
I love my k&d dakota defender. The wait is pretty long, but well worth it. I recently purchased a R.O. Gunleather IWB that comes highly recommended on here. It was only $45 shipped and you will get it in about a week (still waiting on mine).
