From page 61:

"When the barrels were taken from inventory for fitting to the frame, the barrel flats were then milled in and the breech end cut off to the appropriate gauge. Extractor holes, chambers, and shell cuts were then drilled. At this point the barrels were made for either a raised matted rib or ventilated rib. Once the rib was in place the barrels were fitted to the frame and proofed. The gun was then taken, still in the white, to the 40 yard range and fired to determine the point of impact. Model 21s made prior to 1960 were designed to shoot slightly low of dead center. Both barrels were expected to impact the point of aim at the same place."
