Nice. I carry IWB too, really like that carry position. I do not think I would like the appendix carry though, just something about my gun being pointed at my junk and huge artery in my leg all day would not make me feel to comfortable. lol Im looking at this holster for my 1911.

Also, check out the De-Santis intruder IWB, I have that one for my LCP and for $45 its a hell of a holster.
