After I clean the bore, I run an oiled patch through it. Then I let the barrel sit (Breakfree CLP will penetrate somewhat into bore surface) while I clean the barrel's outside surface, slide and frame. After oiling the lube points, I run a mop once through the barrel, which removes excess oil but leaves an extremely thin protective film. Don't like firing a round through an oiled barrel. Yes, you can run a dry patch through the barrel's bore with a jag instead.
