Safety First – The Non-Negotiable Rule
Before diving into the cleaning process, it is imperative to prioritize gun safety above all else. Neglecting safety protocols can lead to severe injury or even death. This section will reiterate the crucial steps to follow every time, before you even think about touching your firearm.
Always begin by verifying that the M&P Shield 9mm is unloaded. This means physically checking the chamber and the magazine. First, remove the magazine from the firearm. Next, visually and manually inspect the chamber to confirm that it is clear of any ammunition. Open the slide and look to confirm that no round is chambered. If the slide locks open, great! This provides even better visibility into the chamber. It’s also recommended to engage the safety, if your Shield model includes one, before beginning the cleaning process.
Always point the muzzle of the firearm in a safe direction, which, generally speaking, means towards an area where an accidental discharge would not cause injury or damage. Make sure the muzzle is consistently pointed in a safe direction throughout the entire cleaning procedure. You can never be too careful.
Safety glasses are essential when cleaning your M&P Shield 9mm. Solvents, cleaning solutions, and even small particles of carbon can easily cause eye injury. Ensure your eyes are protected throughout the process. Gloves are recommended, although not strictly required, to protect your hands from the solvents.
Always clean your firearm in a well-ventilated area. Cleaning solvents often have strong odors and can be irritating. Adequate ventilation helps to minimize exposure to potentially harmful fumes.
Essential Tools and Supplies
To clean your M&P Shield 9mm effectively, you’ll need a few specific tools and cleaning supplies. Having the right gear will simplify the process and ensure a thorough clean.
A cleaning rod is indispensable. This is a solid rod, typically made of aluminum or coated steel, that helps guide cleaning patches and brushes through the barrel. Choose a rod designed specifically for firearms.
You will need a bore brush. This is a brush designed to scrub the inside of the barrel, removing carbon buildup and fouling. A nylon or bronze bore brush suitable for 9mm is what you need. The nylon option is less abrasive, whereas the bronze brush is more aggressive. Replace the brush when it becomes worn.
Cotton cleaning patches are vital for removing debris and solvent from the bore. The size of the patch is important; make sure it’s the right size for a 9mm barrel. It should fit snugly but not excessively tight. You will want a good supply.
Gun-specific cleaning solvent is designed to dissolve carbon, powder residue, and other contaminants. Choose a solvent that is suitable for semi-automatic pistols. Follow the manufacturer’s instructions for use, safety precautions, and disposal.
Gun oil or a high-quality lubricant is essential for proper function. Oil provides lubrication to moving parts, reducing friction and wear. Select a gun oil specifically designed for firearms. Some people choose to use grease in high-wear areas like the slide rails.
A toothbrush or similar cleaning brush will be needed for scrubbing other parts of the pistol, especially the slide, frame, and internal components. A used toothbrush, dedicated for cleaning, is a convenient option.
A cleaning mat provides a protective surface to work on, preventing damage to your firearm and protecting your workspace from spills. Consider a mat that features a diagram of the M&P Shield 9mm for reference during disassembly and reassembly.
As an option, you might find small picks or scrapers useful for removing stubborn residue from hard-to-reach areas. Be careful not to scratch or damage any components.
Field Stripping the M&P Shield 9mm
Before you can begin cleaning your M&P Shield 9mm, you must first disassemble it. This process is often referred to as field stripping. The Shield 9mm is designed for easy disassembly, making the cleaning process relatively straightforward.
Begin by releasing the slide. Make sure the firearm is unloaded. Then, pull back the slide to its rearmost position. Engage the slide catch to lock the slide open.
Next, locate the takedown lever on the left side of the frame. This lever typically sits above the trigger guard. Push the takedown lever downwards. This step unlocks the slide assembly from the frame.
Now, carefully slide the slide assembly forward off the frame. The slide will move forward along the rails. Once the slide clears the frame, you can completely separate the two halves of the pistol.
After the slide is off the frame, the next step involves the recoil spring and guide rod. This assembly is often held in place by spring tension. Remove this assembly carefully, noting its position. It is generally easy to slide the recoil spring and guide rod out of the slide.
The barrel can be removed from the slide. Simply grasp the barrel and lift it out of the slide. There may be a small amount of wiggle or force needed, but the barrel should detach relatively easily.
For more thorough cleaning, you can partially disassemble the slide further. This typically involves removing the firing pin and extractor. Using a punch or specialized tool, you can depress the firing pin retaining plate and slide it out, allowing you to remove the firing pin assembly. The extractor can usually be removed after removing the extractor pin. Warning: This step is only required for very deep cleaning.
Remember the order of each component and the direction it goes. Referring to a diagram or the owner’s manual can be extremely helpful in the beginning.
Cleaning the Components: A Detailed Approach
Now that your M&P Shield 9mm is disassembled, it’s time to clean M&P Shield 9mm.
Start with the slide. The barrel is the heart of the firearm. Use your cleaning rod and the appropriate bore brush to scrub the inside of the barrel. Dip the bore brush in gun cleaning solvent. Run the brush through the barrel from the breech end to the muzzle end. Do this several times to loosen up the fouling.
Next, use cleaning patches. Attach a clean patch to your cleaning rod, and run it through the bore. The patch will absorb the solvent and remove the loosened debris. Repeat this process with clean patches until the patches come out clean, indicating the barrel is free of residue.
Clean other slide components like the breech face and extractor. Use a toothbrush and cleaning solvent to scrub away any carbon buildup or powder residue. Pay attention to any tight spots.
If you have disassembled the firing pin and extractor (optional), clean them as well. Use the toothbrush and solvent to remove any debris.
Moving on to the frame, wipe down the frame with a cloth or rag dampened with cleaning solvent. Focus on removing any dirt, grease, or debris. Use a toothbrush to clean the feed ramp and the area around the trigger.
Magazines, if you are cleaning them, may require a brief moment to maintain. Wipe down the outside of the magazine body. Disassemble the magazine (if applicable – some are easily disassembled, and others are not) to clean the inside. Check the manual to learn how to properly take it apart.
Reassembly: Putting It Back Together
Reassembling your M&P Shield 9mm requires a precise and careful approach. Follow these steps in reverse order to the field stripping process.
Carefully insert the barrel back into the slide, ensuring it is properly seated.
Reinstall the recoil spring and guide rod assembly. Insert the spring guide into the slide and confirm it moves freely.
Align the slide assembly with the frame. Slide the slide assembly onto the frame, ensuring it is seated correctly on the rails.
Lift the takedown lever to lock the slide in place.
Rack the slide several times to ensure smooth movement and operation.
Lubrication – The Key to Smooth Operation
Lubrication is just as crucial as cleaning. Proper lubrication reduces friction, prevents wear and tear, and ensures your M&P Shield 9mm functions smoothly and reliably.
Apply a small amount of gun oil or lubricant to the slide rails. These rails provide the surface upon which the slide moves.
Apply a drop or two of oil to the barrel hood, where it contacts the slide. This also prevents wear and ensures smooth operation.
Lightly lubricate the recoil spring guide rod, facilitating smooth cycling.
Lubricate the trigger mechanism, if easily accessible (refer to your manual).
Wipe off any excess lubricant with a clean cloth. Too much lubricant can attract dirt and debris, which can then hinder performance.
Final Checks and Function Testing
Before loading and firing your M&P Shield 9mm, perform final checks to ensure everything is correctly assembled and functioning properly.
Visually inspect the firearm to ensure all parts are correctly installed.
Perform a function check: rack the slide several times, ensuring the action is smooth. Pull the trigger to confirm proper trigger function. Confirm the slide locks back on an empty magazine (if applicable).
Important Note: Do NOT load live ammunition until you are absolutely certain the firearm is functioning correctly. Always perform the final function check in a safe environment.
How Often Should You Clean Your M&P Shield 9mm?
The frequency of cleaning depends on several factors.
As a general guideline, clean your M&P Shield 9mm after every range session or after firing a significant number of rounds. If you don’t shoot the pistol often, a cleaning every few months, if it has not been used, may suffice.
Factors like the type of ammunition used and the environment in which the pistol is used also influence the frequency of cleaning. For example, dirty or corrosive ammunition may require more frequent cleaning. Exposure to moisture or extreme temperatures may also necessitate more frequent cleaning.
Troubleshooting Common Issues
Cleaning can help prevent and resolve many common firearm issues. However, problems can occasionally arise. If you experience issues such as failure to cycle or light primer strikes, these might indicate a need for cleaning, maintenance, or even a deeper inspection.
