Safety First: A Non-Negotiable Pre-Disassembly Checklist
Before even thinking about touching your Glock 17, you must, and I repeat, *must*, establish a safe environment. This means verifying that the firearm is unloaded. This is non-negotiable.
Remove the Magazine: Press the magazine release and extract the magazine. This is the first and arguably most important step. The magazine is the fuel source of your Glock 17; remove the fuel, and you’ve significantly reduced the risk.
Visually and Physically Inspect the Chamber: With the magazine removed, lock the slide to the rear. Look into the chamber and confirm that it is completely empty. Use a flashlight if necessary to ensure there are no rounds present. Then, physically inspect the chamber by inserting your finger or a cleaning rod to ensure no round is lodged.
Point the Firearm in a Safe Direction: Throughout the entire disassembly and reassembly process, *always* point the muzzle in a safe direction. This typically means pointing it downrange or toward an area where a stray bullet, if one were present, would cause minimal harm. Consider using a designated gun cleaning area or a clear, unobstructed space.
Following the safety checklist, gather your necessary tools. While a Glock 17 is designed to be relatively simple to disassemble, having the right tools makes the process easier and safer.
Glock Disassembly Tool (Recommended): While not strictly necessary, a Glock disassembly tool (often a punch or multi-tool) is highly recommended. It can assist with removing pins and disassembling certain components.
Cleaning Mat/Surface: Work on a clean, flat surface. A cleaning mat provides a good non-slip surface and helps protect the firearm from scratches.
Safety Glasses: Protect your eyes. Safety glasses are crucial during disassembly, cleaning, and reassembly. There’s always a chance of flying debris.
Cleaning Supplies: These include gun cleaning solvent, gun oil or lubricant, a cleaning brush (nylon or bronze), cotton swabs, and clean cloths. The type of cleaning solvent and lubricant is personal preference, but you want something appropriate for your gun.
Field Stripping the Glock 17: The Basic Breakdown
Field stripping, the core of your regular maintenance routine, breaks the firearm down into its primary components. It’s a fundamental skill for any Glock 17 owner.
Removing the Slide: Start with the slide forward and the firearm clear of any ammunition. Grasp the slide and pull it rearward slightly. On both sides of the frame, locate the slide lock levers (often referred to as the slide stop levers). These levers are typically flush with the frame. Pull them downward simultaneously. They may require a slight bit of effort.
With the slide lock levers depressed, the slide should now be free to move forward off the frame. Slide the slide forward, off the frame rails, and away from the frame. Be careful not to pinch your fingers during this process. This separates the slide assembly from the frame.
Disassembling the Slide
The slide assembly contains the barrel, the recoil spring assembly, and the firing pin mechanism. Now, let’s begin disassembling the slide components:
Recoil Spring Assembly Removal
The recoil spring assembly is held in place by tension. Compress the front end of the recoil spring guide, and carefully push it out of the slide. The recoil spring and guide rod are a single, captive unit in the Glock 17.
Barrel Removal
With the recoil spring assembly removed, the barrel can now be removed. Simply lift the barrel out of the front of the slide.
Firing Pin Assembly Removal
Here’s where the Glock tool or a punch becomes useful. On the rear of the slide, you’ll see the firing pin retaining plate (also called the slide plate). Using your tool, push the firing pin safety (a small, spring-loaded plunger located above the firing pin channel) inward. Then, using a small punch (or the disassembly tool), push the firing pin retaining plate down and out of the slide. It may be under spring pressure, so be careful. The firing pin assembly, which includes the firing pin, firing pin spring, spring cups, and firing pin spacer sleeve, can now be removed from the rear of the slide.
Extractor Removal (Optional, but Recommended for a Thorough Clean)
The extractor is the part of the slide responsible for pulling the spent casing from the chamber after firing. The extractor is held in place by the extractor depressor plunger assembly. Depress the extractor depressor plunger assembly and remove the extractor.
Frame Disassembly (Basic)
The frame houses the trigger mechanism, the magazine release, and the slide lock. Disassembling the frame past a simple field strip is generally only necessary for more in-depth cleaning or repairs.
Trigger Mechanism
Remove the trigger pin(s) to release the trigger and trigger bar. Be aware that you may need to use a punch to remove the trigger pin.
Magazine Release
Depress the magazine release button from the right side of the frame. Remove the magazine catch and spring.
Slide Lock/Release
Remove the pin holding the slide lock/release in place.
Parts Identification
Take a moment to familiarize yourself with the parts. The barrel is where the bullet travels. The recoil spring absorbs the energy from the recoil. The firing pin strikes the primer to ignite the cartridge. The extractor removes the spent casing. Recognizing these components will improve your understanding of your firearm.
Cleaning and Maintenance: Keeping Your Glock 17 in Top Condition
Once disassembled, cleaning and proper lubrication are key to the longevity and reliable operation of your Glock 17.
Cleaning Each Component Thoroughly
Slide Cleaning
Start by cleaning the barrel. Use a brush and solvent to remove any carbon buildup, especially near the chamber. Then, clean the slide rails (the surfaces that contact the frame rails), the firing pin channel (ensure it’s free of debris), and the extractor. Clean any carbon or grime, but take care not to scratch any surfaces.
Frame Cleaning
Clean the frame rails (the surfaces that the slide travels on), the trigger mechanism area, and the magazine well. Remove any dirt or debris that may impede function.
Lubricating the Components
Use high-quality gun oil or lubricant. Apply a *small* amount of lubricant to the appropriate areas:
The slide rails on both the slide and frame.
The trigger mechanism components.
The barrel, especially the locking lugs where it contacts the slide.
Reassembly: Putting it All Back Together
Reassembly is essentially the reverse of the disassembly process. Taking your time is key to ensure you do not damage any parts and the firearm functions correctly.
Reverse Field Stripping
Slide Components
Reassemble the firing pin assembly and extractor and reinstall them into the slide.
Install the Barrel and Recoil Spring Assembly
Place the barrel back into the slide. Insert the recoil spring guide and the recoil spring assembly back into the slide.
Frame Assembly
Reassemble the trigger mechanism, and reinstall the magazine release and slide lock/release.
Reinstall the Slide onto the Frame
Align the slide rails with the frame rails. Slide the slide onto the frame until the slide goes onto the frame rails.
Function Check
After reassembly, conduct a thorough function check.
Trigger Function
Pull the trigger to ensure it breaks and resets correctly.
Slide Cycling
Manually cycle the slide several times to ensure smooth operation.
Magazine Release
Insert the magazine and make sure the magazine release works properly.
Troubleshooting: Addressing Potential Issues
Even with careful reassembly, occasional problems can arise.
Common Issues
You might encounter issues, such as the trigger failing to break (meaning the firing pin doesn’t strike), the slide not cycling correctly, or the magazine release malfunctioning.
Troubleshooting Tips
Trigger Issues: Recheck the installation of the trigger bar and connector. Ensure no parts are binding.
Slide Cycling Issues: Ensure the recoil spring is properly seated and installed. Check for any obstructions in the slide or frame rails.
Magazine Release Issues: Verify the magazine catch and spring are correctly installed.
