Machining Extractor Slot:

This cut is generally not needed for most 1911 pistols. The Extractor Clearance cut will generally only be needed on external extractor pistols and some long extractors. Generally, the front of the extractor can be filed down to give proper clearances. But, if you wish to have the clearance cut added to the barrel we give you the option to have it machined before shipping.
