Manufactured in 1902, the third year of production for Colt's first commercially available semi-automatic pistol. The left side of the slide is marked with the standard two-line, two-block patent date and address, with the circled Rampant Colt at the rear. The right side has the standard two-line caliber marking and the serial number is marked on the left of the frame. The slide features the early pattern plunge-milled slide serrations at the rear, generally seen on pistols below approximately serial numbers 1400-1500, but with some overlap in production. It is fitted with blade front and notch rear sight safety in the original configuration, smooth walnut grips which were standard until approximately serial number 2449, and a correct nickeled magazine with 1884 patent date on the base.
