I have a Schuemann barrel, part number GU40CMN0, which is their Government Ultimatch 5" bushingless (bull) barrel in .40 with the Clark/Para Ordnance cut. This is new, never been installed. Details available on the Schuemann Web site
. This has a short chamber, so you can have this made into a 10mm barrel, too. These are great barrels, but I already have 4 1911-pattern pistols in .40 so I don't need to build another.... Asking $150 shipped to the lower 48 states, or trade towards a C-More Railway.
