answer:Just coat all the internal parts as thinly as possible. You don’t need to lubricate, just prevent corrosion. If you use a water-based cleaner, make sure everything is completely dry before oiling. The only exception to this is if the weapon is going to be used in sub-zero temperatures; in that case, remove all oil with solvent before reassembly (at very low temperatures, gun oil acts more like glue). I carry my full-size pistols (M1911, Ruger Super Blackhawk) in shoulder holsters. My Glock 30 (medium/compact .45 ACP) is carried in a behind-the-waistband holster; a carrier with two spare magazines next to it. I sometimes carry a subcompact (like a .45 ACP derringer) in an ankle holster.
