Since you said you have had back problems, and could get away with wearing a back brace, then sounds like a belly band is good option for you. It fits just like a back brace. They come in either black or white, and they have pockets for extras like magazines and such.

Now, that said, I have not carried a 1911 in one - only small revolver or subcompact Glock.
