If you want to try IWB without spending a bunch of money, try the Don Hume 715M. I have them for all of the full sized guns I carry. It's a good quality holster that has a reinforced mouth, something that's very important in an AWB holster.
I carry 200g. Hornady TAP, when I can find it. I couldn't find it a few months ago, so I ended up supplementing it with 230gr. Gold Dots. I didn't want them, but it was all the decent self-defense ammunition I could find.
