Other incidentals included a return to the original caliber stamp on the barrel, eliminating the Single Action Army logo and stamping the appropriate single line or two-line patent dates on the top of the barrel, depending on barrel length. In short, Doug was to re-create what some believe is the finest work Colt has ever produced which for some reason Colt can't seem to do on their own. The Colts that Doug shipped to Prescott for review included 7.5, 5.5 and 4 -inch barrels. Groups with representative factory loads from Black Hills with 250-grain flatnose conical and semiwadcutter lead bullets printed from 2 to 2.5 inches at 25 yards, dead center over the aiming point. The Winchester 225-grain Silvertip factory load put the first five shots in 1.5 inches, the second five in 2.2 inches and the last five in 1.25 inches.
Flat surfaces are perfectly flat with no dished out screw holes or cylinder notches.
The back straps on the grip frame are slightly flattened, eliminating some of the radius that has evolved over the years. The grip frame and the frame are perfectly matched with no gaps, and the radius on the front of the cylinder is a perfect match with the pre-World War II Colts. Variations that might be evident to the serious collector are the shape of the front sight, which varies from the originals, and square notch rear sight that replaced the V notch in the 1930s. Doug does work on original Colt's as well. This Model P was shipped in 1905 and had been refitted with a new barrel and cylinder.
