How to Disassemble a Glock 17

Published on:

Welcome to the “How to Disassemble a Glock 17” blog.

I’ve developed a deep appreciation for the mechanics and maintenance of firearms, particularly the Glock 17. 

In this article, I’ll walk you through the ins and outs of disassembling a Glock 17. Whether you’re a seasoned pro or a curious newbie, understanding how to properly disassemble your Glock is key to ensuring its longevity and performance.

Pre-Disassembly Safety Check

I always emphasize safety first. Here are the crucial steps I never skip:

Magazine Release: This is a vital step. To unload the Glock 17, firmly press the magazine release button. This action should eject the magazine smoothly. It’s essential to do this every single time before handling the gun further.

Chamber Check: After removing the magazine, the next critical step is to ensure the chamber is empty. This involves pulling back the slide to visually and physically check whether the chamber has a round. Never assume the gun is unloaded – always verify. This practice eliminates the risk of accidental discharge.

Trigger Discipline: Before moving on, let’s talk about trigger discipline. It’s a fundamental rule: Never touch the trigger until you are absolutely ready to fire. This discipline is crucial for preventing unintended firing, and it’s a habit that every gun handler should develop and maintain rigorously.

Red Dot Sight Removal: Before you dive into disassembly, gently remove that glock 17 red dot. Treat it like you’re handling delicate china – smooth and steady.

Step-by-Step Guide to Disassemble Your Glock 17

Disassembling your Glock 17 is a straightforward process, but it requires attention to detail. Here’s how to do it:

1. Dry Firing

Aim the gun in a safe direction, away from people or any potential targets. Then, gently squeeze the trigger. This action is mandatory for disassembling the Glock as it releases the tension in the firing mechanism, making it safe to proceed.

2. Handling the Slide

Properly handling the slide is crucial. With your dominant hand, hold the grip of the Glock, placing your thumb under the hilt and wrapping your fingers around the grip. Use your palm to apply gentle pressure on the slide. This position gives you control and stability as you prepare to release the slide.

3. Slide Lock Takedown

With your other hand, locate the slide lock on both sides of the gun’s frame. Carefully pull down these locks simultaneously. While maintaining this position, use your dominant hand to push the slide slightly forward. This action will disengage the slide from the frame, allowing you to slide it off smoothly.

4. Recoil Spring and Barrel Removal

The next step involves removing the recoil spring and the barrel. Carefully lift out the recoil spring, ensuring that it is not damaged. Following the spring, gently remove the barrel from its position in the slide. Handle these components with utmost care, as they are integral to the gun’s functionality.

Post-Disassembly Observations

Once you’ve disassembled your Glock 17, it’s crucial to take some time for a detailed inspection of each component. This step is about more than just looking over the parts; it’s a careful examination to ensure the longevity and functionality of your firearm. Here’s what you should do:

Checking for Wear and Tear: Examine each part closely for signs of wear, damage, or unusual marks. Pay special attention to the barrel, slide, and recoil spring. These areas are prone to wear due to regular use.

Identifying Potential Issues: Look for any small cracks, rust, or debris that might have accumulated over time. Even minor damage can lead to malfunctions or affect the gun’s accuracy.

Regular Inspection Benefits: Consistent and thorough inspections can preemptively identify issues that could lead to malfunctions. This practice is an essential part of responsible gun ownership and maintenance.

Glock 17 Reassembly Tips

Reassembling your Glock 17 is a process that requires precision and attention. It’s not just about putting the parts back together; it’s about ensuring each component is correctly and securely fitted. Here’s how to proceed:

Reverse Order of Disassembly: Start by placing the barrel back into the slide. Ensure it is seated properly. Then, reinsert the recoil spring, making sure it’s positioned correctly and securely.

Reattaching the Slide: Align the slide with the frame rails and gently slide it back into position. This step should be smooth without forcing any parts. If there’s resistance, double-check the alignment.

Function Check: Once the Glock is reassembled, it’s important to perform a function check. Pull the slide back several times to ensure it moves freely and locks as expected. Then, aim in a safe direction and conduct a dry fire. This step confirms that the reassembly was successful and the firearm is operating correctly.

Final Touches

After reassembly, give your Glock one last look-over. Ensure that everything looks as it should and there are no loose parts. This final check is crucial for your safety and the firearm’s reliability.


And there you have it! Disassembling a Glock 17 might initially seem daunting, but with the right knowledge and approach, it becomes a manageable and even enjoyable task.
