Disassembling the SIG Sauer P320

To properly clean your SIG Sauer P320, you will need to disassemble it. The disassembly process consists of field stripping, removing the slide and barrel, separating the frame and slide, and disassembling the Fire Control Unit (FCU).

Field Stripping

Field stripping is the first step in disassembling the P320. Remove the magazine and ensure the chamber is clear. Then, pull the takedown lever down and the slide will be able to move forward off the frame. Push the slide slightly forward and lift it off the frame. Now you have separated the slide from the frame.

Removing Slide and Barrel

To remove the slide from the frame, push the recoil spring assembly forward until it stops. Then, lift the rear of the recoil spring assembly out of its seat, easing it forward, and remove it. You can now pull the barrel and slide forward, separating them completely.

Separating Frame and Slide

With the slide and barrel removed, you can now separate the frame from the slide. Grip the slide firmly and pull it rearward until it aligns with the takedown lever. Push the takedown lever up, and the slide will be released from the frame.

Disassembly of the FCU

To disassemble the Fire Control Unit (FCU), remove the grip module from the frame. Press and hold the takedown lever while sliding the FCU assembly out of the frame. Ensure to follow the manufacturer’s instructions and consult the owner’s manual for a detailed guide on further disassembling the FCU if necessary.

Cleaning Tools and Supplies

Before you start cleaning your SIG Sauer P320, gather the necessary tools and supplies. Here are the essential cleaning tools and supplies you will need:

Necessary Tools

  • Cleaning rod
  • Bore brushes (varying sizes)
  • Cleaning patches
  • Toothbrush or nylon brush
  • Microfiber cloth
  • Punches (optional)
  • Q-tips (cotton swabs)
  • Gunsmithing screwdriver set (optional)
  • Armorers mat or cleaning mat

Cleaning Solvents

Selecting the appropriate cleaning solvents is vital to effectively remove carbon buildup and debris. It is recommended to use solvents specifically designed for firearm cleaning, such as gun-cleaning oils or aerosol cleaning solvents. These solvents are formulated to dissolve carbon residue and lubricate the moving parts of your P320.

Brushes and Patches

Bore brushes of varying sizes are essential for cleaning the barrel of your P320. Use a brush that matches the caliber of your firearm. Cleaning patches are used to apply solvents and remove fouling from the barrel.

A toothbrush or nylon brush can be used to clean the hard-to-reach areas of your firearm, such as the slide serrations, sight channels, and crevices.

Cleaning Rod and Jags

A cleaning rod is used to guide patches and brushes through the barrel. Ensure that the cleaning rod is long enough to pass through the entire length of the barrel. Jags, which attach to the cleaning rod, are used to hold cleaning patches for effective cleaning.

Cleaning the Slide and Barrel

Cleaning the slide and barrel of your SIG Sauer P320 is crucial to maintain its accuracy and reliability. Here’s how you can effectively clean these parts:

Removing Carbon Buildup

Inspect the slide and barrel for carbon buildup. Use a bore brush soaked in cleaning solvent to scrub the inside of the barrel. Move the brush back and forth several times, paying extra attention to the chamber and the area near the muzzle. After scrubbing, run a few cleaning patches through the barrel until they come out clean, indicating the removal of carbon and debris.

Clean the slide by wiping it down with a microfiber cloth or cleaning patches soaked in cleaning solvent. Pay attention to the extractor, firing pin channel, and slide rails.

Cleaning the Breech Face

Use a Q-tip or toothbrush and cleaning solvent to clean the breech face of the slide. Scrub thoroughly to remove any fouling or debris that may hinder proper functioning. Repeat this process until the Q-tip or toothbrush comes out clean.

Lubricating Slide and Barrel

After cleaning, apply a small amount of lubrication to the slide rails, barrel hood, and other areas where metal-to-metal contact occurs. Ensure to use an appropriate gun oil or lubricant recommended by the manufacturer. Apply a thin, even coat to prevent excessive buildup, which can attract dirt and debris.

Cleaning the Frame and FCU

Cleaning the frame and Fire Control Unit (FCU) is equally important for the proper functioning of your SIG Sauer P320. Here’s how you can clean these components effectively:

Removing Debris and Grime

Inspect the frame for any debris, grime, or carbon buildup. Use a toothbrush or nylon brush soaked in cleaning solvent to scrub the hard-to-reach areas. Pay close attention to the trigger assembly, grip module, and magazine well. Wipe down the frame with a microfiber cloth or cleaning patches to remove any excess solvent and debris.

Cleaning Trigger Assembly

To clean the trigger assembly and other small parts of the FCU, disassemble them according to the manufacturer’s instructions. Use a toothbrush or nylon brush soaked in cleaning solvent to scrub each part thoroughly. Ensure to remove any carbon buildup or residue that may affect the trigger’s smooth operation.

Lubricating Frame and FCU

After cleaning, apply a light coat of lubrication to the necessary components, such as the trigger assembly, sear, and other contact points in the FCU. Apply the lubricant sparingly to prevent excessive buildup, which can attract dirt and debris.

Reassembling the SIG Sauer P320

Now that you have thoroughly cleaned all the components of your SIG Sauer P320, it’s time to reassemble them. Follow these steps to ensure a proper reassembly:

Assembling the FCU

Reassemble the Fire Control Unit (FCU) by following the manufacturer’s instructions or the reverse order of disassembly. Ensure that all components are aligned correctly and properly seated.

Joining Frame and Slide

Align the slide rails with the corresponding grooves on the frame. Slide the frame and the slide together, ensuring a smooth and secure fit. Push the slide rearward until it locks into place. Perform a visual inspection to ensure the slide is fully seated and properly aligned with the frame.

Installing Slide and Barrel

Reinstall the barrel by sliding it into the slide and aligning it correctly. Push the barrel all the way back until it locks into place. Align the recoil spring assembly with its seat on the barrel lug. Push it rearward, compressing the spring until it snaps into place.

Functional Check

Perform a functional check to ensure proper reassembly. Check the slide’s functionality by manually cycling it back and forth several times to ensure smooth operation. Ensure that the trigger, magazine release, and other fire controls function properly without any binding or sticking. If everything checks out, your SIG Sauer P320 is now ready for use.

Proper Storage and Maintenance

Proper storage and regular maintenance are essential for preserving the performance and longevity of your SIG Sauer P320. Here are some tips to keep in mind:

Storing the Firearm

When not in use, store your SIG Sauer P320 in a secure and dry location. Consider investing in a sturdy gun safe or secure storage container to prevent unauthorized access and protect your firearm from environmental elements. Always store it separately from ammunition.

Regular Maintenance

Regularly inspect your P320 for any signs of wear, damage, or excessive fouling. Clean and lubricate the firearm after each use to prevent the buildup of carbon residue and ensure smooth operation. Follow the manufacturer’s recommended maintenance schedule and perform regular maintenance tasks, such as replacing springs or worn components, as necessary.
