To clean a Davis P-380 auto pistol, first ensure the firearm is unloaded by checking the chamber and magazine. Disassemble the pistol according to the manufacturer's instructions, typically including removing the slide and barrel. Clean the barrel using a bore brush and solvent, then wipe down the slide and frame with a soft cloth to remove dirt and debris. Finally, lubricate the moving parts lightly with gun oil before reassembling the pistol.
