I have a question for you guys. I just purchased a Colt 1911 Augusta Arsenal rework pistol with the orignal shiping box and receipt. Everything on the pistol is correct except for the rear sight. Its a two dot rear sight. Its parked like the rest of the pistol and matches the rest of the pistol perfectly. My question is this. Did they give the option to the buyer to have the original notch sight or an upgraded sight? If I have to get a notch sight will it match up ok? Pistol was manufactured in 1918. Thanks for your help.
