Things You'll Need
Instructions
Make sure the gun is unloaded. Never clean a loaded gun.
Disassemble the handgun. How you do this depends on the type of semi-automatic handgun you own. Refer to your owner's manual. Once disassembled, the gun will be in 4 main parts: the frame, the slide, the barrel and the magazine.
Run a solvent-soaked patch through the barrel, and follow with a bore brush. Then run a lubricant-soaked patch through the barrel, followed by a dry patch.
Wipe exterior and inside of slide, the frame and trigger or hammer areas with lubricant, followed by a dry cloth. Apply 1 or 2 drops of lubricant to the rear of each slide channel and the decocking lever pin. Apply grease to hammer face and frame rails.
Reassemble the handgun. Slide the action several times to work in lubricant until it slides smoothly. Wipe any excess lubricant with a dry, clean cloth. Apply a small drop of oil to all moving parts.
