What You’ll Need (click "Gun Cleaning Gear" in navigation menu):

Firearm cleaning solvent
Gun oil or lubricant
Bore brush and cleaning rod
Cleaning patches
Nylon or brass brush
Microfiber cloth
Cotton swabs or Q-tips

Step 1: Ensure Safety

Before handling or cleaning your PX4 Storm, it's crucial to ensure it is completely unloaded:

Remove the magazine.
Pull the slide back to eject any chambered round and lock the slide open using the slide stop.
Visually and physically inspect the chamber to confirm the gun is unloaded.
Once verified, release the slide forward.

Step 2: Field Strip the PX4 Storm Sub-Compact

1. Disassembly Lever:

Ensure the hammer is cocked, and the safety is in the "off" position.
Hold the pistol securely, and with your other hand, rotate the disassembly lever downwards (located on the frame just above the trigger guard).
Once the lever is fully rotated, the slide will be free to move forward off the frame.

2. Remove the Slide:

Slowly guide the slide assembly forward off the frame.

3. Remove the Recoil Spring and Barrel:

Compress and remove the recoil spring assembly from the slide.
Lift the barrel from the slide.

Step 3: Clean the Barrel

Apply cleaning solvent to a bore brush and insert it into the barrel from the chamber end.
Run the brush through the barrel several times to remove carbon buildup and debris.
Follow with a cleaning patch attached to a cleaning rod, pushing it through until patches come out clean.
Use a cotton swab to clean the feed ramp and chamber area, removing any excess fouling.

Step 4: Clean the Slide

Apply solvent to the inside of the slide, focusing on the breech face, extractor, and slide rails.
Use a nylon brush to scrub these areas thoroughly.
Wipe down the slide with a microfiber cloth to remove any remaining solvent and debris.

Step 5: Clean the Frame

Apply solvent to the rails, trigger mechanism, and other small areas where dirt or fouling may accumulate.
Use a nylon brush or cotton swabs to clean these areas, ensuring all dirt is removed.
Wipe the frame with a clean microfiber cloth.

Step 6: Clean the Recoil Spring Assembly

Wipe down the recoil spring and guide rod with a solvent-soaked patch or cloth to remove any fouling or dirt.
Ensure the spring is clean and free from debris before reassembling.

Step 7: Lubricate the PX4 Storm

Lubrication is crucial to the smooth functioning of your PX4 Storm Sub-Compact. Apply oil sparingly to the following areas:

Barrel exterior – Apply a light coat of oil, particularly around the locking lugs.
Slide rails – Add a small amount of oil to ensure smooth movement between the slide and frame.
Recoil spring – Lightly oil the spring and guide rod.
Trigger mechanism and internal moving parts – A drop of oil will help prevent wear and ensure smooth operation.

Step 8: Reassemble the PX4 Storm Sub-Compact

Insert the barrel back into the slide.
Place the recoil spring assembly back into position.
Align the slide with the frame rails and guide it back onto the frame.
Once in place, rotate the disassembly lever back into its original position to lock the slide in place.

Step 9: Function Check

Rack the slide to ensure it moves freely and locks back when empty.
Perform a trigger function check by dry firing the gun to ensure smooth operation. Always ensure the firearm is unloaded before dry firing.

Step 10: Final Wipe Down

After reassembling, give your PX4 Storm a final wipe-down with a microfiber cloth to remove fingerprints, excess oil, or solvent residue. This also helps prevent corrosion.

Conclusion

Following these steps will help maintain your Beretta PX4 Storm Sub-Compact in peak condition. Regular cleaning ensures reliability, accuracy, and longevity, helping your firearm perform at its best when you need it most.
