I agree with having ramped barrels, the major drawback being expense. Unless you buy a base gun with a ramped barrel, like a Kimber Stainless Target II, one then has to have a very competent smith mill the frame. Then price ramped vs. non-ramped barrels...
I have not found any major drawbacks to non-ramped 1911s...ramped is nice but expensive.

If you start with a 9mm/Super frame, then it all works. If you start with a .45 frame, when you get the 9mm/.38 Super barrels, often the barrel with over-hang the frame at the feed ramp by a thousandth or two. One way to get around that is to cut the little dimple like Colt's been doing with some of their new guns, but that's not always a sure fire solution. Best to just start with the .38 Super feed ramp, the you can make it all work much easier.
