The slide presents polished flats with a matte top and rounds, vertical rear serrations, and no front serrations, offering a period-correct Series 80 appearance.

U.S.A." An inspector numeral "1" is stamped on the right front trigger guard.

Full-checkered wood grip panels with gold Colt medallions round out the traditional look. Capacity is 7+1, and this example includes one 7-round magazine.
