Yup, I have a Colt WWI remake also and shoot traditional. This problem was bad with my gun too. I polished "fit" the safety and the back of the grip so that when the safety is depressed there are no sharp edges along the area that comes in contact with the web between thumb and finger. No more bleeding, pinching, and gouging. Just run your finger around the edge of the back-strap safety with it pushed down and the bottom area below the hammer and you will know where to polish.
