I'm sure someone out there would make it for you, have you ever tried carrying a gun in the small of your back? I tried it when I first got my carry license, found out real quick that unless you stand all day and walk where ever you go it wont be comfortable. It will also print very bad if you bend over, much more than any other way of carrying.

I find that IWB strong side conceals very well, if I were to need something that concealed ever more than that pocket carry of and airweight j-frame would be my choice.
