Someone needs to build a 45 pistol that is only as thick as said barrel.

Because it is just way uncomfortable to carry my doublestack 1911 IWB.

There's your problem.

I don't think it's possible to have a double stack 45 that's as thin as the barrel. How thick is the mag? And then on top of that thickness, you've got to add the frame for the handle, and then the grips/scales.

Yep, single stack.

For many years, I carried a SA XDm 9mm which is a plastic, double stack 9mm. Even in compact form, it was a big, heavy PITA to carry. I have a couple/few times carried a full size, all steel, 1911 (single stack) .45. It was easier and more comfortable to carried than the old XDm. An even smaller single stack 9mm, plastic gun is even easier to carry.

I agree with JB, get a light weight, commander (or officer) sized, single stack, and even in .45 you'll be much happier than with your double stack.
