Why Cleaning Your Smith & Wesson M&P Shield is Important

You might think, “I’ve fired my M&P Shield a few times and it’s still performing well. Why bother cleaning?” Let’s explore the reasons why cleaning this specific firearm is crucial.

One of the primary reasons we clean our firearms is to ensure optimal performance during use. Left uncleaned, your M&P Shield can accumulate residue from bullets and primers. Here’s why that matters:

  • This buildup can affect the gun’s accuracy over time, altering your aim and shot consistency.
  • More concerning, an excessively dirty firearm presents a potential safety hazard. Grime can cause parts to stick or move sluggishly, increasing the chances of malfunction.

Secondly, cleaning is key for extending your firearm’s lifespan. You’ve invested money in your Smith & Wesson M&P Shield, right? It’s only rational to make that investment last. Regularly cleaning the internal and exterior parts of your gun protects it from damage caused by corrosion. Even the smallest particles of unburned powder can pull moisture from the air, leading to rust and other forms of deterioration.

Lastly, a well-maintained firearm is a reflection of responsible ownership. You wouldn’t drive a car for years without ever changing the oil, would you? Similarly, regular cleaning showcases your commitment to safe and responsible firearm use. It’s not merely about performance and longevity; it’s about safety and responsibility too.

Up next, I’ll walk you through a step-by-step guide on how to effectively clean your M&P Shield. We’ll cover everything from what tools you’ll need, to the best methods for cleaning every individual component. Stay tuned to keep your M&P Shield in top-working condition and extend its life.

Materials Needed for Cleaning

Effectively cleaning your Smith & Wesson M&P Shield starts off with gathering the right materials. A proper cleaning kit can make all the difference. Let’s dig into the list of fundamental items you’ll need.

  • Gun Cleaning Solvent: This liquid works wonders in dissolving residues that can’t be swept away. A bit of chemistry at play, gun cleaning solvents target residues specifically so the firearm can have a clean slate, literally!
  • Lubricating Oil: To keep your firearm running smoothly, lubricant is a must. After a good clean, applying lubricating oil ensures parts move easily against each other, reducing wear and tear.
  • Bore Brushes: Grit and grime can take cover in hard-to-reach places. Bore brushes, however, are not deterred. They get in there and scrub the bore clean, whether it’s caked on carbon or other stubborn residues.
  • Cleaning Rod: Or accompanying partner to bore brushes. The cleaning rod carries the brushes into the hard-to-reach spots and acts as the driving force needed to scrub away.
  • Patches and Cleaning Cloth: To wipe up after the brushes, you’re going to need patches that’ll fit into the gaps easily. A cleaning cloth will serve you to polish and finish up the exterior.
  • Utility Brushes: They’re versatile in cleaning different components of the firearm – making sure every nook and corner is attended to.
  • Disassembly Tools: Depending on your M&P Shield model, you might need specific tools to help disassemble the firearm for a thorough clean.

Securing these materials ahead of time helps streamline the cleaning process and ensures you’re ready for any buildup that’s come to call your firearm home.

Do keep in mind that your Smith & Wesson M&P Shield is a unique firearm and as such, there might be other supplementary cleaning items beneficial. Always best to check the manufacturer’s cleaning recommendations, as there may be preferences for specific products or tools to ensure the best upkeep.

With your cleaning materials at the ready, there’s just one thing left – getting down to the actual cleaning of your Smith & Wesson M&P Shield.

Step 1: Unloading the Firearm Safely

When it comes to cleaning the Smith & Wesson M&P Shield, safety is the top priority. The first step, therefore, is to ensure your firearm is unloaded. It’s an undeniable, crucial rule of gun maintenance to never, under any circumstances, service a loaded gun.

First off, point your firearm in a safe direction. Aiming your firearm towards a brick wall, tree, or the ground helps eliminate the risk of injury or damage, should an accidental discharge occur.

Next, let’s engage the safety by moving the mechanical safety switch, commonly located on the firearm’s frame, from the “Fire” to “Safe” position. In this state, the firearm’s trigger mechanism is blocked, preventing it from releasing the hammer or striker.

Moving on, you should release the magazine by pressing the magazine release button. It’s typically located within thumb’s reach and marked by an image of a bullet with an arrow. Remove, and place it aside. Remember, removing the magazine does not mean the firearm is unloaded. There might still be a round in the chamber.

To fully unload, pull back the slide. This extracts the chambered round, if there is one. Keep pulling back the slide until it’s locked open with the chamber visible. Look inside the chamber to make sure it’s empty. It’s better to double-check for peace of mind and, more importantly, safety.

Remember, gun maintenance is more than just about keeping your firearm in top condition – it’s also about polishing your knowledge and adherence to gun safety. So let’s move to the next step, disassembling your Smith & Wesson M&P Shield piece by piece. Stay tuned.

Step 2: Disassembling the M&P Shield

Having established the significance of safety measures and proper gun unloading, it’s time to take the Smith & Wesson M&P Shield apart. The disassembling process is relatively simple, but it’s crucial to follow every step with precision and care.

Start by Removing the Slide

Proceed initially by locking back the slide. A lever present on the left-hand side of the firearm is leveraged for that purpose.

  • Engage the slide-lock lever.
  • Inspect the chamber for any remaining rounds.

Once you’ve verified the chamber’s empty, it’s okay to release the slide. Next, you gotta lower the firearm’s takedown lever, making sure to pivot it downwards. Fast after that, guide the slide forward off the frame.

Go Ahead With Field Stripping

After you’ve removed the slide, it’s time to field strip the pistol.

  • Use your fingers to lift the recoil spring assembly out of the slide.
  • Push the barrel slightly forward, then lift it upwards.

Doing so separates the barrel from the slide, completing the field stripping.

Easy to note that disassembling the M&P Shield doesn’t require special tools. Maintenance, including thorough cleaning, becomes straightforward once you master these steps.

Don’t forget to retain a clean, safe area for all disassembled firearm parts. A well-organized workspace aids efficient restoration of the firearm.

Remember, I said we’re focusing on regular cleaning, which involves field stripping only. Further disassembly, like taking apart the firing mechanism, isn’t necessarily undertaken for routine maintenance.

Step 3: Cleaning the Barrel and Slide

Now that we’ve safely unloaded and disassembled the firearm, it’s time to get down to the business of cleaning the barrel and slide of the M&P Shield. Remember, rifling within the barrel is the heart of accuracy in a firearm. A dirty barrel might not only affect accuracy but also reliability. So let’s get started.

Begin with the barrel. Use a bore brush attached to a cleaning rod. Apply a high-quality gun solvent (your choice, but branded ones preferably) and run it through the full length of the bore. Ensure you’re going in from the back (breech) to the front (muzzle) to avoid damaging the muzzle crown. Do this few times to lose the stubborn grime.

I recommend switching to a jag and a patch next. Soaked in solvent, these patches will pick up the loosened debris on their way out. Make sure to change patches often. Repeat until the patch comes out clean.

Next, apply a light coating of gun oil to a fresh patch and run it through the bore, wrapping up the barrel cleaning process. This will help prevent rust and ensure smoother operation.

For the slide, the process is similar but not identical, as we’re dealing with different parts. I suggest using a small nylon brush soaked in solvent to scrub each nook and cranny of the slide, getting rid of any grime or residue. Pay special attention to the breach face – the part of your slide which is directly in contact with the back of your ammunition; it’s typically most dirty.

A tip here: I use a Q-tip soaked in solvent to reach the hard-to-reach areas of the slide. Once you’re satisfied, wipe off any excess solvent and apply a thin coat of oil across the slide. Remember, over-lubrication can attract more dirt, hence keep it ‘thin’.

Lastly, don’t forget to check and clean your extractor. It’s the small hook-like part which pulls the expended casing out of the chamber. Keeping the extractor clean is crucial to avoid any misfiring or ejecting issues.

And there you have it – a cleaned barrel and slide. You’ll notice I didn’t touch on reassembling – that’ll be the next step.

Step 4: Cleaning the Frame and Grip

Next up, after cleaning the barrel and slide, we move on to the frame and grip of your Smith & Wesson M&P Shield. Like always, it’s crucial that you maintain a clean workspace while operating on this crucial part of the firearm.

To kick off, obtain a small nylon brush and Q-tips, which will be our primary cleaning tools for this stage. Soaking the brush and Q-tips in a gun cleaning solvent will yield optimal results.

Firstly, I tend to start at the top of the frame, working my way down to the grip. It’s best to pay special attention to the slide rails as they house moving parts. Brush these areas thoroughly, breaking up any visible crust or filth. Remember, the cleaner these parts, the smoother the operation.

Next, reach down into the mag well with your solvent-soaked Q-tip. You’d be amazed at how much gunk can accumulate there, especially if you’ve been practicing your quick reloads. Working the Q-tip around will ensure any built-up residue is effectively scrubbed away.

Turning our attention now to the grip — this is where your hand supports the firearm. It’s also one of the most overlooked parts in the cleaning process. A simple wipe off isn’t enough, I suggest using the small brush to get into the small nooks and crannies. You’ll want to be as thorough as possible.

Now that these parts are free of dirt, we apply a light coating of gun oil. This not only improves the performance of the moving parts but also provides a layer of protection against rust.

Keep in mind, any excess oil should be wiped off. A firearm dripping with gun oil might look nice in the case, but in the field, it’ll likely collect more dirt than it repels.

From our barrel and slide to the frame and grip, we have made excellent headway in the cleaning process. And with this level of detail, the next steps should flow effortlessly. In our next segment, we’ll tackle the reassembly. Stay tuned for that.

Step 5: Lubricating the Gun

Now that we’ve given our Smith & Wesson M&P Shield a thorough cleaning, it’s onto the next significant step – lubrication. Proper lubrication ensures not just smooth operation of the gun but also prevents it from rapid wear and corrosion.

When it comes to lubricating a firearm, use specifically designed gun oil. Avoid using oils that aren’t intended for firearms since they can cause harm and lead to malfunctions. The lubrication process is relatively simple, yet it’s crucial to be attentive to the details to ensure the best outcome.

Primarily, lubricate the portions of the gun that have metal-to-metal contact. A small amount of oil goes a long way; applying excess oil might attract dirt and grime, contributing to operational difficulties.

Follow these steps to lubricate your gun:

  1. Slide: Apply a modest amount of oil on the slide rails and spread it around using a Q-tip.
  2. Barrel: Apply a thin coat of oil on the outside of the barrel and inside the barrel, use a patch soaked in oil through the bore, thereby reducing the friction for the bullets.
  3. Frame: Little oil on the places where the frame rubs against the slide.

I’ll emphasize here, when oiling your firearm, less is often more. An over-lubricated gun can become a dirt magnet, causing more harm than good.

Moving forward, we’ll delve into properly reassembling your Smith & Wesson M&P Shield, a crucial step to ensure the effectiveness and longevity of your firearm. But before that, let’s give a couple of minutes for the oil to soak in and settle. This waiting period is an excellent opportunity to tidy up your workspace, ensuring all your cleaning materials are properly stored and the area remains accident-free.

By this point, believe me, you’ll start to appreciate the mechanical beauty of your firearm even more, knowing that you’ve contributed to its upkeep and premium performance. It’s an engaging routine, one that truly introduces you to the finer points of owning and maintaining a Smith & Wesson M&P Shield.

Step 6: Reassembling the M&P Shield

Now that your Shield’s lubricated and sparkling clean, let’s go ahead with the reassembly. It’s crucial to follow all instructions to the letter – each step ensures the longevity and performance of your firearm.

Start by examining the slide. On a properly cleaned firearm, it’s devoid of any dirt or residual oil. Once you’ve confirmed the cleanliness, take the barrel. Remember, the muzzle end goes first into the slide, aligned with the front end. Push it through until it sets against the slide. Following that, insert the guide rod assembly. Replace the spring near the muzzle end. Now, all it takes is a little push and a twist into place.

With that, your slide’s ready. Moving on, let’s reassemble the frame. For this, set your attention to the sear deactivation lever – make sure it’s not in the downward position. Next, grab your slide and align it with the rails on the frame. After ensuring the slide is resting correctly on the rails, push it all the way back.

Now comes an important part – reconnecting the take-down lever. If it’s right where it should be – on the left side of the frame – pivot it clockwise until it’s no longer vertical but horizontal. Double-check its position – it must be parallel to the ground.

In the end, ensure the slide lock lever is pulled downwards, and you gently release the slide moving forward. If there’s a satisfying click into place – you’ve done it right! Always double-check everything. A well-assembled firearm not only performs impeccably but boosts your safety and confidence as well.

In the next segment, we’ll discuss how to verify if the firearm is functioning correctly after the reassembly process.

Step 7: Final Inspection and Function Test

Now that we’ve successfully reassembled the Smith & Wesson M&P Shield, it’s time to give it a final inspection and test its functionality. This final check is key to ensuring that nothing was misplaced or overlooked during the cleaning and lubricating process.

Begin with a visual inspection. Look for any parts that might be out of place or not fully secured. Check that the slide is properly aligned with the frame, and the slide lock lever is in the correct position.

Next, test the functionality of the firearm. Here’s what I recommend:

  • Insert an unloaded magazine into the firearm.
  • Rack the slide to simulate the action of chambering a round.
  • Verify that the slide lock lever is functioning correctly. It should automatically lock back on the last round.

After going through these steps, you should feel confident that your Smith & Wesson M&P Shield is clean, lubricated, and ready for use. Failure during the function test might suggest that there are outstanding issues that were possibly overlooked during the reassembly process. In that case, revisit our previous steps.
