Safety Precautions

Before we get into the step-by-step process of cleaning your FN Five-seveN, it’s essential to observe some critical safety precautions. As a gun owner, safety should always be your top priority. Ensuring that the firearm is unloaded before you start the cleaning process is a must.

To verify that the gun is unloaded, you’ll first need to remove the magazine. Push the mag release button and pull it out. With the magazine removed, pull back the slide and hold it open to inspect the chamber. If there’s no round in the chamber, your gun’s unloaded and ready to be cleaned. Never skip this critical safety step.

Aside from ensuring your gun is unloaded, you should always wear protective equipment during the cleaning process. The solvents and oils often used when cleaning guns can be harmful if they come into contact with your skin or eyes. Using gloves and safety glasses can protect you from potential harm.

Another crucial safety consideration is your working environment. Always work in a well-ventilated space when cleaning your gun to avoid inhaling harmful solvent fumes. Ventilation can be as simple as working near an open window or using a small fan.

Next, it’s important to keep your gun cleaning tools in a dedicated place. This ensures you can find everything you need quickly and importantly, it prevents any potentially hazardous mishaps from misplaced objects.

Now that you’re aware of these essential safety precautions, let’s delve into the process of successfully cleaning your FN Five-seveN.

Field Stripping the FN Five-seveN

Before digging into the deep cleaning, it’s important to initiate a key process called field stripping. This involves disassembling key parts of the FN Five-seveN without going into intricate details. It’s a fundamental step that you should ideally perform after each use.

My first directive to field strip the FN Five-seveN is to work on a flat, stable, and clean surface. Having an easy-to-clean material like a gun cleaning mat can prove beneficial here. This not only helps in keeping the parts organized but also protects the surface from any operational residue or cleaning product stains.

Next, ensure your FN Five-seveN is unloaded. Remember, safety should always be your priority. To unload, point the gun in a safe direction and lock the slide back in place. Check for any rounds in both the chamber and the magazine. If there are none, the firearm is safe for field stripping.

Transitioning to the actual disassembly task, let’s start focussing on the slide. Push the slide slightly rearward till the slide catch lever aligns with the notch on the left side of your slide. Rotate the slide catch lever upward until the slide assembly is free. Now gently push the slide assembly forward off the frame. It’s essential to manage the components with utmost care to prevent misplacement or damage.

Subsequently, grasp the recoil spring assembly by the large end and pull out of the recess in the slide. Follow it with turning the barrel lug to the locked position and lift the barrel from the slide. At this point, you’ve now successfully field-stripped your FN Five-seveN.

These basic steps should get you through field stripping process of FN Five-seveN. But don’t stop here. We still have more ground to cover in deep cleaning this high-precision firearm. Always remember that regular maintenance not only prolongs the life of your firearm but also ensures its reliable operation at the range or in the field. So let’s continue our deep dive.

Cleaning the Barrel and Slide

Having stripped your FN Five-seveN, it’s now time to dive deeper into its individual components, starting with the barrel and slide. These parts bear the brunt of the explosion that propels the bullet, making them particularly susceptible to dirt and residue.

Begin with the slide. Armed with your cleaning solution and a quality firearm brush, give it a thorough scrubbing. Allowing the solution to sit for a minute or two before brushing will help break down those stubborn residue deposits. However, avoid the temptation to soak it overnight, as this can lead to rust development.

Be mindful of the breech face and extractor, as these areas can harbor hidden buildup that can affect the firearm’s performance. Some extra care and attention here can go a long way in maintaining the overall reliability of your FN Five-seveN.

Moving on to the barrel, the same basic principles apply. Apply your cleaning solution sparingly, focusing on areas where buildup is most likely to occur. Namely, the breech, feed ramp, and bore. A bore brush, an essential tool in any firearm cleaning kit, will be your best friend in tackling the bore of the barrel.

Remember to run the brush through in the direction of the bullet path. This prevents the bristles from bending or breaking and aids in a thorough clean. Following up with a bore snake or cleaning patch will ensure any loosened residue is removed.

It’s worth noting that cleaning the barrel of a FN Five-seveN requires more than a simple scrub. The process involves running a cleaning patch through the bore until it emerges clean, an indication that all residue has been effectively removed.

Given the nature of the FN Five-seveN, maintenance plays a vital role in function and longevity. So, consider getting your gun professionally cleaned annually along with your regular cleaning schedule. This ensures optimum performance and extends the lifespan of your firearm.

In the next section, we’ll move on to cover the frame, offering insights and tips for its effective maintenance.

Cleaning the Frame and Magazines

Moving on to the frame, you need to remember: this component takes a lot of the operational stress. Proper cleaning and maintenance won’t just keep your FN Five-seveN working—it’ll ensure the firearm’s long-lasting performance.

Cleaning the frame can be tricky. Don’t use abrasives or hard metal tools. They can damage the frame’s finish. Instead, opt for cleaning with a soft nylon brush. If there’s built-up residue, gently using a plastic tool can get the job done.

When it comes to the internals of the frame, compressed air is your best friend. Use it to blow away any dust or debris in the crevices. A spray of a good quality gun cleaner can also assist. Apply it sparingly and let it do its magic before wiping away.


  • Do not dunk the whole frame in water or cleaning solution.
  • Never try to disassemble the frame any further—it’s not designed for it. Stick to what’s accessible.

Switching gears: let’s talk about the magazines. They’re often an overlooked part of firearm cleaning but warrant equal attention. You’ll need to disassemble them for thorough cleaning.

Here’s a straightforward process to do it:

  • Remove the baseplate carefully.
  • Slide out the spring and follower.
  • Clean each component using a soft brush and the recommended gun cleaner.

Be gentle in the process. Magazines have a few delicate parts that can affect the feeding if damaged. Reassemble once clean, ensuring everything goes back in the right order.

Note: It’s advisable to check the feed lips and follower for wear regularly. If you notice any cracks or deformation, it’s time for a replacement.

Moving forward, we’ll focus on the final stages of maintaining your firearm.

Lubrication and Reassembly

After you’ve made sure your FN Five-seveN’s frame and magazines are clean, it’s time to move on to the next step: lubrication and reassembly. Proper lubrication of your firearm is vital for its functioning and overall longevity. It minimizes wear and tear and ensures the smooth operation of moving parts.

You’ll want to use a high-quality firearm lubricant for this step. I prefer using a lubricant that’s specifically designed for handguns. Make sure to apply the lubricant sparingly. Avoid the common mistake of over-lubricating as this can attract debris and cause functionality issues.

Apply lubricant to the slide rails, barrel, and the moving parts of your FN Five-seveN. It’s always a good practice to give a bit of attention to the parts where metal-to-metal contact frequently occurs.

Once properly lubricated, it’s time to reassemble your firearm. When reassembling, work in the reverse order of disassembly. Follow these step-by-step instructions for a hassle-free reassembly:

  1. Reinsert the barrel and recoil spring into the slide.
  2. Mount the slide onto the frame’s rails.
  3. Move the slide back until it locks into place.
  4. Reinsert the magazine.

Always remember to handle your firearm gently, especially during reassembly. Rough handling can often lead to damage of delicate parts and will eventually affect your weapon’s performance.

After reassembly, it’s crucial to conduct a basic function test. Be sure to check that the slide moves freely and locks back correctly, the trigger resets, and the magazine inserts and ejects smoothly.

If the firearm passes the basic function test, you’ve successfully cleaned, lubricated, and reassembled your FN Five-seveN.
