I don't buy that. The operating sequence of the cylinder stop is the same, whether it is single or double action, and it drags the cylinder in either case.

I believe the difference in some guns developing more of a line than others is a combination of a couple of factors. Total cycles of the firing mechanism, from "round count" or dry fire or just playing with the action; and the microscopic contour of the cylinder stop's top edge, whether is is 'sharp' on the edges or slightly rounded, are the greatest contributors to a turn line. The spring tension of the cylinder stop spring would also have an effect; even though the springs are all essentially the same, a minute variation in spring tension, practically unmeasurable but not enough to affect operation, could over time cause more wear.
