I have a matched pair of Colt .45 ACP 1911s that I carried through tout my military career after out of jump school. My Grand Dad and Dad bought them for me as a graduation gift.
I have a Ruger that is pretty good but it not in the same class as the Colts. I have heard Springfields are pretty good.
It kind of depends on what caliber you are looking at. In the 9 mm Guns than Ruger has a great one. The .45 ACP just is not as balanced as the Colts.
