Understanding Glock Sights
Glock pistols come equipped with a variety of sight types, each offering distinct advantages and disadvantages. Understanding the different options available is crucial for selecting the right sights for your specific needs and shooting preferences.
Types of Glock Sights
At the heart of the Glock’s aiming system are the sights. The standard sights, often referred to as iron sights, come in several configurations. The factory sights, while functional, are often considered basic. These generally feature a rear sight with a U-shaped notch and a front sight with a simple post. These sights are designed for general use but may not be ideal for everyone.
Aftermarket sights offer a plethora of alternatives to improve accuracy and target acquisition. Among the most popular upgrades are sights with enhanced visibility, such as those with three-dot configurations, where a dot is positioned on the front sight and on either side of the rear sight notch, creating a clear alignment. Other options include sights with colored inserts or tritium vials that glow in low-light conditions, making them easier to see in various lighting environments. There are also sights that use a U-notch rear sight with a vertical bar or dot front sight, which some shooters find easier to align.
While iron sights are the most common, other optical sights are available for Glock pistols. While this article focuses on iron sight replacement, it’s worth briefly mentioning the world of red dot sights (RDS). These are small, battery-powered optics that project a red dot onto the target, providing an exceptionally clear and fast aiming point. Red dots are rapidly growing in popularity, and many Glock owners choose to have their slides milled to accommodate them.
Importance of Choosing the Right Sights
The selection of sights is a crucial decision. The best choice is determined by several factors, including your shooting style and the intended use of your Glock.
For personal defense, sights that offer rapid target acquisition, even in low-light situations, are usually preferred. This might involve tritium sights or those with bright, easy-to-see markings. For competitive shooting, you might opt for adjustable sights, which allow for precise adjustments to elevation and windage. These can give an edge when fine-tuning for accuracy at varying distances. If you primarily use your Glock for target practice, you might favor sights that offer a precise sight picture, such as those with smaller front posts or rear notches.
The sight picture, the visual alignment of the front and rear sights, is paramount. Evaluate how quickly and easily you can acquire the sight picture with each option. Also, consider the visibility of the sights in different lighting conditions and against various backgrounds. Finally, think about the durability of the sights. Are they built to withstand the rigors of daily use? Consider options like steel sights, known for their robustness, particularly if you plan on carrying your Glock. Choosing the right sights can make a significant difference in your shooting performance.
Required Tools and Safety Gear
Before embarking on the process of changing your Glock sights, assembling the correct tools and equipment is essential. Proper preparation not only streamlines the process but also safeguards your firearm and ensures your safety.
You will need a sight pusher or an installation tool. Several types are available. A dedicated sight pusher is typically the preferred choice. A sight pusher uses mechanical leverage to push the sights out of the dovetail slots, minimizing the risk of damage to your slide. Make sure the one you select is designed for Glocks, as the dovetail dimensions and the position of the sights vary. You can also use a bench vise with appropriate jaws designed to hold your Glock slide safely.
Some gun owners, especially if working on a budget, opt for a punch and hammer, although this method requires more finesse and care to avoid scratching or damaging the slide. Gunsmithing punches are specifically designed for this purpose and often have a soft tip that will prevent marring. If you use this method, choose the appropriately sized punch, and use controlled taps with a hammer, moving slowly.
Whether you use a sight pusher or a punch and hammer, a gunsmithing vise is an invaluable tool. Securing the slide in a vise provides a stable platform, making it easier to apply the necessary force without the slide moving. A good vise should have soft jaws or jaw pads to prevent scratches.
Essential safety gear includes protective eyewear to shield your eyes from any debris or projectiles during the process. Gloves are optional, but they can improve your grip on the slide and protect your hands. A set of Allen wrenches or a screwdriver may be required if your new sights use screws for adjustment or installation.
You’ll also need threadlocker, such as Loctite Blue. This is applied to the threads of any screws used to secure the sights, preventing them from loosening due to recoil or vibration. And lastly, you may need cleaning supplies to clean the slide if any debris gets into the dovetail.
Safety Precautions
Safety is paramount when working with firearms. Every step must be approached with extreme caution, and following established safety protocols is non-negotiable.
The Importance of Firearm Safety
Always treat every firearm as if it is loaded. This fundamental principle of firearm safety must guide every interaction. Always keep the muzzle pointed in a safe direction, away from yourself and others. Never point the gun at anything you don’t intend to shoot.
Before beginning any work on your Glock, you must verify that it is unloaded. Remove the magazine, then visually inspect the chamber to ensure it is empty. Open the slide and look through the ejection port and make sure the chamber is clear. This is the single most important safety step. Keep your finger off the trigger until you are ready to shoot. This applies during every step of the process of changing sights, and at all times when handling the firearm.
Workspace and Preparation
Choose a workspace that is well-lit and organized. A clean environment reduces the likelihood of losing small parts and helps prevent accidents. A clear work surface is crucial. Protect your firearm by placing it on a work mat designed for gunsmithing. This provides a soft surface that prevents scratches. Before you begin, ensure the area is free from distractions and unnecessary clutter.
Step-by-Step Guide: Removing the Old Glock Sights
With the right tools and your workspace prepared, it’s time to remove the old sights.
Removing the Rear Sight
First, secure the slide in the gunsmithing vise. Place the slide in the vise so that the dovetail for the rear sight is accessible and supported by the vise jaws. Use the sight pusher. Follow the tool’s instructions and make sure it’s properly aligned on the rear sight. Many sight pushers are designed to apply force only to the base of the sight, not the sight itself. Slowly and carefully apply pressure to push the sight out.
If you are using the punch and hammer method, carefully position the punch on the side of the rear sight, making sure the punch is making contact with the base and not the top. Tap the punch with a hammer, applying controlled force. The sights should push out from left to right. Use small, controlled taps. Avoid excessive force, as this can damage the slide. Clean the dovetail slot of any debris with a brush or a cleaning tool.
Removing the Front Sight
Secure the slide in the vise again, or on your workspace. If your front sight has a retention screw, unscrew and remove it. This screw typically secures the front sight to the slide. Use a screwdriver or Allen wrench of the correct size. Most Glock front sights can then be removed by simply pushing them out from the side. If your front sight is stubborn, you can use a sight pusher or punch to remove it, similar to the rear sight. Then, clean the area where the front sight was housed.
Step-by-Step Guide: Installing the New Glock Sights
Now it’s time to install your new sights.
Installing the Rear Sight
Carefully insert the new rear sight into the dovetail slot. The orientation of the sight is important. Ensure the sight is aligned correctly. Many sights have a specific orientation, and installing them backwards can lead to issues.
Use the sight pusher. Align the pusher tool with the new rear sight, again ensuring that the tool only pushes on the base of the sight. Apply steady pressure, and the sight should slide into place. Monitor the sight’s alignment as it is pushed in. If the sight is difficult to install, double-check the alignment and the tools.
If you are using a punch and hammer, carefully position the punch, applying pressure from right to left, and tap the punch with your hammer. Again, proceed with small, controlled taps, and avoid excessive force. Ensure the rear sight is installed straight and flush with the slide.
Installing the Front Sight
Insert the new front sight into the front sight post. Secure the new front sight with the retention screw, if applicable. For the retention screw, use threadlocker to ensure it does not come loose. Apply a small amount of threadlocker to the threads of the screw before installation. Use a torque wrench, if available, and tighten the screw to the manufacturer’s recommended specifications.
Final Steps and Adjustments
With the sights installed, it’s time to finish the process and ensure everything is working properly.
Inspecting the Sights
Inspect the new sights for proper installation and security. Verify that the sights are straight, flush with the slide, and securely in place. Ensure there is no misalignment or looseness. The front and rear sights need to be straight so that the gun fires accurately.
Test Firing and Zeroing
Now, take the firearm to a safe shooting range. Test fire the Glock to see if the shots are hitting where you’re aiming. This process is called zeroing. If you are not hitting the intended target, some sights have adjustable components on the rear sight, such as screws. Some can be adjusted for windage and elevation. If your shots are too far to the left or the right, you can adjust the rear sight left or right. If they are low or high, you can adjust the rear sight to move the point of impact up or down.
Cleaning and Maintenance
After the installation and test firing, clean the firearm. Thoroughly clean the slide. Regular maintenance is key to ensuring the continued function and reliability of your Glock.
Troubleshooting
Even the most experienced gun owners sometimes encounter problems. Here’s a look at some common issues and how to resolve them.
Common Issues
Difficulty removing or installing the sights is a common problem. Sight misalignment can also occur. And sometimes, sights can get damaged during the process.
Solutions and Tips
If you have difficulty removing the sights, double-check your tools and techniques. Ensure that the pusher or punch is properly aligned. If you are using a punch and hammer, consider using a sight pusher if available. Also, if you’re having trouble, make sure you are pressing the sight out from the correct direction.
For sight misalignment, double-check the installation instructions. Ensure the sights are flush with the slide and not canted at an angle. If the sights are too tight, you may need a specialized tool to push them in. If the sight is damaged during the installation, replace the sight.
If you are uncertain or uncomfortable with any aspect of the process, seek the help of a qualified gunsmith. Gunsmiths have the expertise and tools to perform the work safely and correctly. Do not hesitate to consult a professional.
