Proper firearm lubrication focuses on protection against corrosion and reducing friction wear with a microscopic film. Modern synthetic oils and CLPs are superior to older natural oils. Over-oiling attracts debris, creating an abrasive compound that accelerates wear, making frequent cleaning more critical than heavy lubrication. In extreme environments like cold or dusty deserts, running a firearm dry may be preferable to avoid malfunctions.
