Just finished reading an article in the June American Rifleman on the Wiley Clapp Colt/TALO Commander. There is a pic that shows what appears to be a fully throated chamber mouth that "features a shallow trough in the throat to enhance feeding." It looks like a crossbreeding between a throated barrel and an older GI barrel:) I am unfamiliar with this concept. Can someone bring me up to speed on this mod? Part of me says Colt wouldn't do it if it was snake oil. OTOH - I can't say that I've seen it in any other high end 1911s (not that I look at a lot:)

TIA
