Step 1: Ensure the P320 is Unloaded

Safety is the utmost priority when handling firearms. Follow these steps to ensure your P320 is unloaded:

1. Remove the magazine by pressing the magazine release button.

2. Pull back the slide and visually inspect the chamber to confirm that no ammunition is present.

Step 2: Disassemble the P320

Field stripping the P320 allows you to clean it effectively:

1. Lock the slide to the rear by pulling it back.

2. Push the takedown lever down to the 6 o’clock position.

3. Release the slide forward and remove it from the frame.

4. Remove the recoil spring assembly from the slide.

5. Take out the barrel from the slide.

Step 3: Clean the Barrel

1. Apply cleaning solvent to a bore brush and insert it into the chamber end of the barrel.

2. Run the bore brush through the barrel several times to dislodge carbon fouling and debris.

3. Follow up with a cleaning patch on a cleaning rod, pushing it through from the chamber to the muzzle until the patch comes out clean.

4. Wipe down the exterior of the barrel with a clean cloth to remove any grime or residue.

Step 4: Clean the Slide

1. Use a nylon brush dipped in solvent to scrub the inside of the slide, focusing on the rails, firing pin channel, and extractor.

2. Clean the external surfaces of the slide with a cloth or towel to remove any dirt or oil.

Step 5: Clean the Frame

1. With the slide removed, use a nylon brush and solvent to clean the frame, paying special attention to the trigger assembly, magazine well, and inside of the frame.

2. Wipe the frame thoroughly with a soft cloth to remove any excess solvent or debris.

Step 6: Clean the Recoil Spring and Guide Rod

1. Wipe the recoil spring and guide rod with a cloth soaked in solvent to remove any accumulated dirt.

2. Ensure they are completely dry before reassembly.

Step 7: Lubricate the P320

Proper lubrication is key for optimal operation:

1. Apply a light coat of gun oil to the barrel (both inside and outside).

2. Lubricate the rails of the slide where it contacts the frame.

3. Apply a small amount of lubricant to the recoil spring to ensure smooth operation.

Step 8: Reassemble the P320

1. Reinsert the barrel into the slide.

2. Attach the recoil spring assembly back into the slide.

3. Align the slide with the frame and slide it back into position until it locks.

4. Push the takedown lever back to its original position to secure the slide.

5. Perform a function check by pulling the trigger (ensure the gun is unloaded), cycling the action, and ensuring everything operates smoothly.

Step 9: Final Wipe Down

Use a microfiber cloth to give the exterior of the Sig Sauer P320 a final wipe-down, removing any excess oil, fingerprints, or moisture.
