Hey Gunners! welcome to My How To Clean a Glock 19 Blog.

My aim is to guide you through a straightforward, thorough cleaning process that ensures your Glock 19 remains in top-notch condition. 

We’ll delve into the specifics of each cleaning step, emphasizing the importance of regular maintenance for optimal performance. 

Glock 19 Field Stripping & Cleaning

1. Getting the Right Tools Together

In my experience with the Glock 19, having the right tools is half the battle won. Whether you’re dealing with a Glock 19 or any other model in the Glock family, this holds true. 

The toolkit? Pretty standard: gun cleaner, gun oil (steer clear of motor oil), a soft cloth (an old t-shirt is perfect), a cleaning rod or bore snake, nylon brushes, and enough cleaning patches. It’s essential to use quality materials since they make the cleaning process more efficient and protect the gun from wear.

2. The All-Important Safety Check

Safety can never be overstated. Every time I clean my Glock, I follow a strict routine: remove the magazine, double-check it’s empty, and thoroughly inspect the chamber. 

This isn’t just a cursory glance; I make sure there’s no ammunition in the gun. When I’m 100% confident it’s clear, I proceed. 

A critical step is pointing the gun in a safe direction before pulling the trigger during the disassembly. This habit has become second nature, ensuring both my safety and that of those around me.

3. Field Stripping the Glock

Having field-stripped numerous Glocks, I find the process quite intuitive. The initial step is to apply backward pressure on the slide and simultaneously pull down the takedown lever. The slide then easily separates from the frame. 

This leaves you with four main components: the frame, slide, guide rod, and barrel. Handling each part carefully is crucial, not only to avoid damage but also to maintain the integrity of the firearm. 

In my time using the Glock 19, I’ve learned that careful handling during disassembly and reassembly keeps the gun in optimal condition for longer periods.

Step-by-Step Guide: How To Clean A glock 19

1. Guide Rod: The Starting Point

I always begin with the guide rod. A thorough wipe with a clean cloth does the job. It’s generally less dirty, but I don’t overlook it. Keeping it clean ensures smooth functioning, something I’ve come to appreciate during my shooting sessions.

2. Barrel: The Grime Hub

The barrel usually harbors the most grime. I’ve found that using a cleaning patch dampened with a gun cleaner attached to a cleaning rod is the most effective method. I insert it from the chamber end and push it through several times. 

Switching to a fresh patch and repeating the process until it emerges clean assures me that the barrel is free of residue. This step is crucial for maintaining accuracy, a fact I’ve confirmed through countless rounds at the range.

3. Slide: The Workhorse

Next, I focus on the slide, particularly the rails. These parts undergo significant wear and tear. Using cleaning patches combined with a nylon brush, I meticulously remove all dirt and debris. 

A vital tip I’ve learned is to keep the muzzle pointing downwards, preventing any particles from entering the firing pin channel. This helps maintain the reliability of the firearm, something I rely on during my shooting practices.

4. Frame: The Foundation

For the frame, a slightly damp cloth usually suffices to remove any stubborn dirt. It’s also an opportunity to inspect for any damage or wear. 

Regular checks like this have often helped me spot issues early, preventing bigger problems down the line.

5. Lubrication

In my experience, a conservative approach to lubrication works best. Too much lubricant can attract dirt and degrade performance, something I’ve learned through trial and error. I usually skip lubricating the guide rod and focus on the barrel and slide rails. 

A single drop of quality gun oil on these parts is sufficient. This step is critical for maintaining a smooth operation, a fact that becomes evident in the smoothness of the slide action during firing.

Lubrication: Less is More

In my routine with the Glock, I’ve learned that a modest amount of lubrication is most effective. Overdoing it can indeed lead to more dirt accumulation and issues with functionality. 

So, I carefully apply just a drop of gun oil to the barrel and the slide’s rails, focusing on areas where there’s metal-to-metal contact. 

This step is critical for ensuring smooth operation, which I’ve particularly noticed during rapid firing sessions. The right amount of lubrication makes the slide action noticeably smoother and more reliable.

Reassembly and Function Testing

Reassembling the Glock is a task I’ve become quite adept at. The barrel and guide rod are reinserted into the slide, and then the slide is carefully aligned and slid back onto the frame. 

After reassembly, a comprehensive function test is crucial. This includes checking the trigger safety to ensure it’s functioning correctly. It’s a step I never skip, as it directly relates to the reliability of the firearm. 

During my shooting practices, I’ve found that a well-maintained Glock, one that’s been correctly reassembled and tested, performs exceptionally well, with consistent firing and reliable safety features.

Final Verdict

In conclusion, maintaining your Glock 19 through regular cleaning and proper lubrication is key to ensuring its longevity and reliable performance. 

My experience in the field has taught me that a well-maintained Glock is a shooter’s best asset. Remember, it’s not just about cleaning; it’s about understanding your firearm and treating it with the care it deserves. 

Whether you’re at the range or relying on it for personal defense, a clean and well-maintained Glock 19 will rarely let you down. Embrace the routine, respect the process, and enjoy the dependable performance of your Glock 19.


How often should you clean your Glock 19?

You should clean your Glock 19 after each firing session, before its first use, and at least once a month if not used regularly to ensure optimal performance.

What is best to clean Glock with?

The best way to clean a Glock is by using a small gun cleaning brush for the frame and slide, followed by a patch wet with a reliable gun lubricant like Hoppe’s, and then apply a drop of lubricant to the trigger bar end.

Is dry firing a Glock 19 bad?

Dry firing a Glock 19 is generally safe, but for extended sessions, it’s advisable to use a snap cap or dummy round to prevent potential wear.

Can a Glock 19 rust?

Although Glocks have a rust-resistant finish, they are not immune to rust. Regular maintenance is necessary to prevent and address any rust issues.
