  2. Fully depress the magazine release button located on the left side of the grip.
  3. Remove the magazine by pulling it out of the grip.

Ensuring the chamber is empty:

  1. While keeping your finger off the trigger, pull the slide back slightly to visually inspect the chamber.
  2. Look into the chamber to verify that there is no ammunition present. Ensure the barrel is empty.

Verifying the safety mechanisms:

  1. Set the Glock 17’s slide into the rearward position.
  2. Check that the striker, located at the back of the slide, is visible and in a cocked position.
  3. Slide the selector switch, located on the left side of the frame, upward to engage the trigger safety. This will prevent the trigger from moving rearward.

By following these steps, you can confidently proceed knowing that your Glock 17 is unloaded and the necessary safety measures are in place. Remember to always treat every firearm as if it were loaded.

Step 2 – Field Stripping the Glock 17

Field stripping your Glock 17 is the process of disassembling it to its basic components for cleaning and maintenance. This allows you to access the slide, barrel, and frame individually. Here’s how to field strip your Glock 17:

Removing the slide:

  1. Point the Glock 17 in a safe direction.
  2. Pull the slide back slightly, maintaining pressure on it.
  3. Depress the slide lock lever located on the left side of the frame, just above the trigger guard.
  4. While keeping the slide lock lever depressed, ease the slide forward off the frame.
  5. Release the slide lock lever, allowing it to return to its original position.

Taking out the recoil spring and guide rod:

  1. Hold the Glock 17’s slide with the ejection port facing up.
  2. Grasp the recoil spring assembly, located at the front of the slide.
  3. Push the recoil spring assembly slightly downward and forward to disengage it from the barrel.
  4. Slowly release the recoil spring assembly, allowing it to extend fully.
  5. Lift the rear of the recoil spring assembly and remove it from the slide.

Detaching the barrel:

  1. While holding the slide with the ejection port facing up, tilt the barrel upward from the slide.
  2. Gently ease the barrel forward, away from the front of the slide.
  3. Once the barrel is free from the slide, remove it completely.

By following these steps, you have successfully field stripped your Glock 17, allowing for easy access to the individual components for cleaning and maintenance.

Step 3 – Cleaning the Slide and Components

Now that your Glock 17 is field stripped, it’s time to clean each component thoroughly. The slide, in particular, requires extra attention as it houses critical parts such as the firing pin and extractor. Here’s how to clean the slide and its components:

Wiping down the slide and exterior:

  1. Use a clean microfiber cloth to wipe down the slide’s exterior, removing any dust, debris, or fingerprints.
  2. Pay close attention to the rails, as these areas may accumulate dirt and residue.

Cleaning the firing pin channel:

  1. Apply a small amount of cleaning solvent to a cleaning patch or cloth.
  2. Insert the patch or cloth into the firing pin channel, located at the rear of the slide.
  3. Push the patch or cloth through the channel several times, ensuring the solvent reaches all surfaces.
  4. Repeat the process with a clean, dry patch or cloth to remove any excess solvent.

Inspecting and lubricating the extractor:

  1. Inspect the extractor, located at the rear of the slide, for any visible signs of wear, damage, or debris.
  2. If necessary, use a nylon or brass pick to remove any dirt or residue from the extractor.
  3. Apply a small amount of lubricating oil to the tip of your finger or a cotton swab.
  4. Apply the lubricant to the extractor, ensuring it is evenly distributed.

By properly cleaning the slide and its components, you are ensuring that these critical parts function smoothly and reliably when the Glock 17 is fired.

Step 4 – Cleaning the Frame and Trigger

Cleaning the frame and trigger assembly is essential for maintaining the overall performance of your Glock 17. Over time, carbon buildup and debris can accumulate in these areas, potentially affecting the trigger pull and firearm function. Here’s how to clean the frame and trigger assembly:

Detailing the frame:

  1. Use a soft cloth or cleaning patch to wipe down the frame, removing any dirt or residue.
  2. Pay close attention to the grip texture, as this area may accumulate sweat or oils from prolonged handling.
  3. Inspect the frame for any signs of wear or potential issues, such as cracks or damage.

Removing carbon buildup on trigger components:

  1. Locate the trigger mechanism housing, located within the frame.
  2. Use a nylon brush or toothbrush to gently scrub the trigger bar and other components for any carbon buildup or debris.
  3. Pay close attention to the engagement surfaces and any areas that hinder the trigger’s function.

Lubricating key areas:

  1. Apply a small amount of lubricating oil to a cotton swab or soft cloth.
  2. Apply the lubricant to the trigger bar, trigger connector, and any other areas that require lubrication.
  3. Ensure the lubricant is evenly distributed, and wipe away any excess oil or grease.

By thoroughly cleaning and lubricating the frame and trigger assembly, you are promoting smooth operation and reducing the risk of malfunctions or trigger issues.

  2. Insert the bore brush into the barrel from the chamber end.
  3. Push the brush through the barrel in a back-and-forth motion, ensuring it makes contact with all surfaces.
  4. Repeat this process several times to loosen and remove any fouling or debris.

Scrubbing the barrel’s interior:

  1. After using the bore brush, insert a clean cotton patch onto a cleaning rod.
  2. Push the patch through the barrel using a jag or slotted tip, ensuring it makes contact with all surfaces.
  3. Continue pushing clean patches through the barrel until they come out relatively clean, without visible dirt or residue.

Inspecting for fouling or damage:

  1. After cleaning, visually inspect the barrel’s interior for any remaining fouling or damage.
  2. Use a light source and peer through the barrel, looking for any signs of obstruction or wear.
  3. If any stubborn fouling remains, repeat the cleaning process using solvent and brushes.

By thoroughly cleaning the barrel, you are promoting optimal accuracy and reducing the risk of malfunctions caused by fouling or debris.

Step 6 – Reassembling the Glock 17

Now that each component of your Glock 17 is clean and lubricated, it’s time to reassemble the firearm. Follow these steps to ensure proper reassembly:

Attaching the barrel and recoil spring:

  1. Hold the Glock 17’s slide with the ejection port facing up.
  2. Insert the cleaned barrel into the front of the slide, aligning the lug on the barrel with the corresponding recess in the slide.
  3. Push the barrel forward until it locks into place.
  4. Place the recoil spring onto the rear of the barrel, lining up the end with the notch on the barrel.

Sliding the slide back into place:

  1. Hold the Glock 17’s frame with one hand and the slide with the other hand.
  2. Position the slide onto the frame, aligning the rails on the slide with the corresponding grooves on the frame.
  3. Push the slide rearward until it locks into place.

Ensuring proper alignment:

  1. Engage the safety mechanisms by setting the selector switch downward and releasing the slide.
  2. Perform a function check by racking the slide fully to the rear, releasing it, and engaging the trigger to ensure it resets correctly.
  3. Conduct a final visual inspection of the fully reassembled Glock 17, making sure all components are aligned and properly seated.
