2/10/25 – This is an original Colt 1911 Barrel that is “S” marked indicating it is a Commercial to Military Barrel. 5/10 bore, does not come with link or pin. Excellent external finish. From coolgunsite.com – S” stamping forward of the lugs 711,000 to 935,000 (approximately): Most or all of the Commercial to Military conversion pistols have the “S” marked barrel as they were originally Commercial pistols and would have had “S” for “Sales” marked barrels. Colts apparently used most of its remaining commercial parts in pistols following the C to M conversions, as Commercial slides (With commercial markings) can be seen in pistols up through the Canadian group.The S marked Colt barrels will sometimes exhibit an almost fire blue color on the chamber area. Apparently these barrels had already had the chamber area polished out to the white, and then were heat blued to meet military requirements.” –
