If you’re a proud owner of a Ruger Mark IV, you know it’s not just about the shooting—it’s about maintenance too. Keeping your firearm clean and well-maintained is crucial for its longevity and performance. That’s what we’ll delve into today.

In this article, I’ll guide you through the process of cleaning your Ruger Mark IV. We’ll go step by step, making sure you’ve got all the bases covered. From disassembling to cleaning and then reassembling, we’ll cover it all.

Disassembling the Ruger Mark IV

Having raised the importance of maintaining a Ruger Mark IV, let’s delve into the first step of the process: disassembling. A Ruger Mark IV, like any firearm, is a complex piece of machinery. It’s made up of numerous small parts that need to be removed and cleaned individually. But don’t fret – I’ll guide you through this!

Upon starting, ensure the firearm is unloaded. Safety should always be your priority when handling firearms. Push the safety lever to its “safe” position. Then, press the magazine release button – you’ll find it on the left side of the firearm. Remove the existing magazine.

Let’s proceed to actually taking apart the Ruger Mark IV. If you look at the back of the pistol, you’ll see a button under the rear sight. This is the takedown button. Press this and gently lift the barrel upward, away from the firearm’s grip frame. Be sure to handle each part carefully to keep them in top shape.

Next, remove the bolt. To do this, slide it to the rear of the receiver and lift it up and out. Remember, take care not to force anything. If it doesn’t move, don’t push it. The rule of thumb is to confirm each part’s correct alignment before removal.

It’s worth mentioning: some Ruger Mark IV models have a few more features – threaded barrels, loaded chamber indicators, etc. If yours has these, consult the user manual for specific disassembly instructions.

There you have it! You’ve just disassembled your Ruger Mark IV. In the following section, I’ll walk you through how to clean these components properly.

Gathering the Necessary Cleaning Supplies

Before we dive into the details of cleaning your disassembled Ruger Mark IV, it’s essential to ensure you have all the right cleaning supplies on hand. Having a well-equipped cleaning kit will make the cleaning process smoother and more effective. Here’s a list of the necessary supplies:

  • Gun cleaning solvent: This fluid effectively loosens and removes the build-up of residue from the gun’s bore and other parts.
  • Lubricating oil: It’s used after cleaning to ensure that the gun operates smoothly and is protected from corrosion.
  • Cleaning rod: A cleaning rod helps to apply the cleaning solvent and patches to the interior parts of the gun such as the barrel.
  • Patch holder and cleaning patches: Patch holders are attached to the cleaning rod and used with cleaning patches to scrub the interior parts of the gun.
  • Bore brush: It’s used to scrub the inside of the barrel.
  • Utility brushes: These are vital for scrubbing the exterior parts and harder-to-reach areas of the gun.

Now that we’ve identified what’s essential for a comprehensive Ruger Mark IV cleaning kit, let’s also consider a few additional items that while not necessarily required, can enhance the cleaning process.

An apron or old clothes protect you from oil and solvent stains. Rubber gloves protect your hands. A cleaning mat or old cloth provides a clean workspace and keeps small parts from getting lost.

Additionally, a gun vise can help secure your firearm while cleaning. While not necessary, it’s a helpful tool for hands-free gun cleaning.

So, it’s pretty clear, a good cleaning job starts with having the right cleaning supplies. In the next section, I’ll guide you through the proper way to use these supplies to get your Ruger Mark IV cleaned and ready to operate at its best.

Cleaning the Barrel and Slide

Once you’ve gathered your essential Ruger Mark IV cleaning supplies, the true task begins. It’s important to approach this with patience and care. Remember, your firearm’s effectiveness depends heavily on its cleanliness.

First off, focus on the cleaning rod. Attach the bore brush to it, and then immerse the brush in your gun cleaning solvent. Now you’re all set to clean the barrel. Start with inserting the rod into the barrel, from back to front. Keep doing this several times, until you’re convinced that the barrel is free from any grime or gunpowder residue.

After you are done with the preliminary scrubbing, it’s time to use the patch holder and cleaning patches for a more thorough cleaning. I would suggest you keep the cleaning patches handy. Dip a patch in the solvent, attach it to the patch holder, and run it through the barrel. Do it a few times with new patches until you are satisfied that all the dirt has been captured.

Next, let’s switch our focus to the slide. Use a utility brush to gently scrub the slide. Pay close attention to the crevices and corners. The utility brush dipped in solvent should do the trick for you, but an old toothbrush would also work! After scrubbing, use a clean, dry cloth to wipe down the slide and remove any excess solvent.

Quick Tip: Don’t forget to lubricate the barrel and slide after cleaning. It might be a bit boring to do, but it’s an essential step in increasing your firearm’s lifespan. Use the lubricating oil for this and ensure that you apply a light, even coat all over.

By carefully following these guidelines, you’ll keep your Ruger Mark IV operating at its best. Though it might seem like a tedious chore at times, regular cleaning is a must-do for any responsible gun owner.

Cleaning the Frame and Other Components

Keeping the frame of your Ruger Mark IV in optimal condition isn’t just about aesthetics; it’s about ensuring the firearm’s function and longevity. The frame, often overlooked due to the focus on the barrel, deserves equal attention and care.

To start, make sure you have a well-lit area so you don’t miss any grimy spots. Grab your utility brush or an old toothbrush. You’ll also need some gun cleaning solvent.

Pro-tip: Avoid using home cleaners or products unapproved by firearm manufacturers.

As I do, apply some solvent onto the toothbrush, and gently scrub all areas of the frame. Be meticulous here – pay attention to the small nooks and crannies. You’d be surprised at how much grime can build up in these spots.

Once you’ve scrubbed the entire frame, it’s time to wipe it down. A dry, clean cloth should do the trick but make sure it won’t leave any fibers or residue behind. Give it a once-over, making sure all solvent and grime are removed.

Beyond the frame, don’t forget about the magazine and its components. First, disassemble the magazine according to your Ruger Mark IV manual. Clean the follower, the base plate, and the inner tube the same way as above, with a brush and some solvent. Then considering using compressed air to blow out any stubborn debris.

Remember: Regular cleaning of your Ruger Mark IV’s frame, magazine, and all other components is key to its functionality.

The final step is not a conclusion but a continuation in our Ruger Mark IV maintenance journey. After all, cleaning a firearm isn’t a ‘clean and forget it’ task. It’s an ongoing commitment for every responsible gun owner. Now that we’ve taken care of the barrel, slide, and frame, I’ll guide you on the next integral step of reassembling the gun and how to correctly store it in my subsequent sections. Keep this in mind as you continue to read on mastering gun maintenance.

Lubricating the Ruger Mark IV

After cleaning, lubrication is the next critical step in caring for your Ruger Mark IV. It’s like giving your car engine oil: it keeps things running smoothly and prevents wear and tear. On a firearm, the right lubrication reduces friction between moving parts, minimizes wear, prevents rust, and ensures reliable operation.

Lubricating a gun

Begin with the bolt assembly.

Firstly, you’ll want to place a small drop of gun oil on the extractor of the bolt assembly. Doing so reduces the friction between these parts, enhancing the firearm’s efficiency and reliability. It’s important though, not to over-lubricate since excess oil can attract dust and debris, causing more harm than good.

For the frame.

Then, lightly oil the frame rails, and don’t forget to add a tiny amount to the sear and hammer pivot. Again, it’s critical not to overdo it. A little lubrication goes a long way in keeping your Ruger Mark IV in top form.

And, for the barrel.

Finally, run a patch soaked in oil through the barrel. It’s not enough to just clean the barrel; you need to oil it for maximum protection. This step will not only ensure smooth loading and firing, but also help prevent rust and corrosion.

Reassembling the Ruger Mark IV

Reassembling the Ruger Mark IV is as delicate a process as disassembly, yet it’s not hard once known. Did you take note of how it came apart? Shuffle through the memory if you did, it’ll come in handy. Don’t fret if you didn’t – that’s what I’m here for. Let’s take it step by step, ensuring you bring your Ruger Mark IV back to form flawlessly.

First, grab the bolt assembly. Slip it back into the receiver, easing it through the back. You’ll feel it slide into a position where it’s supposed to sit. Now, get your hands on the frame. Attach it securely back onto the receiver. It’ll fit snug and tight – just how it’s supposed to.

Next, reattach the barrel to the frame. Be gentle; don’t force it in place. It’s easy to know it’s sitting right. When the Ruger Mark IV starts taking its original shape, that’s your cue. Do not force anything; let the pin find its place.

How about the magazine? Don’t forget it now. It’s the last piece of this reassembly puzzle. Ensure you have the right orientation and slowly slide it back into its place.

Don’t skip on checking your work. Ensure there are no parts left out. Go through each step again if you are not sure. You don’t want to wind up with a non-functioning firearm or, worse, a dangerous one.

While doing this, keep in mind to keep the trigger locked until the entire process is complete. Handling firearms require extreme caution, and I you need to remember this at all times.


So there you have it. Cleaning a Ruger Mark IV isn’t as daunting as it might seem. It’s all about taking it one step at a time, reassembling each part with care, and always prioritizing safety. Remember, don’t rush the process. Be gentle with each piece, and double-check your work. It’s crucial that each part is properly reassembled before you unlock that trigger. With these tips in mind, you’ll maintain your Ruger Mark IV in tip-top shape, ensuring its longevity and performance. Happy cleaning, and always handle your firearms responsibly.
