From what I've read, these came from Brownells. It has the Series 80 safety cutouts. Similar to the Colt Competition slide that CDNN sold, but this one is not marked "competition". Government model slide marked "Colt Government Model" under the ejection port. Has Heinie Slant Pro night sights (figure 8) installed - dim, but some light to them. Also Colt 45 Auto barrel that is unaltered, Bbl link, FP & spring, and FP stop that has been fit to the Heinie cutout. Polished flats. Bluing is in excellent condition. Slide looks to be unaltered other than the sight cuts. $195 shipped for everything shown, except the orange rag.
