Preparing for the Task

Before you commence cleaning, ensure you are in a well-ventilated area with ample lighting. Your cleaning kit should include a cleaning rod, bore brush, patch holder, cleaning patches, gun oil, and solvent.

    • Run a clean patch through the barrel to wipe out the loosened residue. Repeat with fresh patches until they come out clean.
  2. Slide Cleaning:
    • Use a small brush or a clean cloth with solvent to clean the slide’s interior and exterior surfaces, focusing on the breach face and rails.
  3. Frame Cleaning:
    • Wipe down the frame with a cloth lightly dampened with solvent. Pay special attention to the rails and any other areas where residue may accumulate.
  4. Recoil Spring Cleaning:
    • Wipe down the recoil spring with a clean, solvent-dampened cloth to remove any debris or residue.


  • Barrel and Slide:
    • Apply a thin layer of gun oil to the barrel, barrel hood, and the slide‚Äôs interior surfaces.
  • Frame:
    • Lightly lubricate the frame rails and other moving parts.
