Preparation and Safety First: Your Priority
The foundation of any successful gun project is a commitment to safety. This cannot be stressed enough.
First, always unload your Glock and verify it is empty. Remove the magazine, lock the slide back, and visually and physically inspect the chamber to ensure no ammunition is present. Repeat this process several times during the project. Make absolutely certain the firearm is unloaded. Keep the muzzle pointed in a safe direction at all times.
Next, wear appropriate eye protection. Safety glasses are an absolute must. Flying debris is a real possibility when working with tools, and protecting your eyes should be your top priority.
Choose a well-lit and clean workspace. A cluttered or poorly lit environment can increase the risk of accidents. A workbench or sturdy table is ideal.
With your safety measures in place, you can gather the necessary tools and materials. The right equipment will make the job significantly easier and safer. The following is a comprehensive list, though some items are optional:
Assembling the Necessary Tools and Materials
The tools needed for this project are generally straightforward. A good set of tools will ensure a smoother and more successful sight swap.
Glock Sight Pusher (Recommended): This is the single most important tool. A dedicated sight pusher tool is specifically designed to remove and install sights without damaging your slide. Various brands offer different models. A good sight pusher will provide a secure grip on the slide and a precise way to apply pressure to the sights. Look for a pusher compatible with the Glock model you are working on.
Punch and Hammer (Alternative for Rear Sight Removal): If you don’t have a sight pusher, or are on a budget, a set of punches and a small hammer will be needed to remove the rear sight. Invest in a quality punch set, with various sizes. Brass punches are often preferred to minimize the risk of scratching the slide.
Small Punch (for Front Sight Roll Pin): Many Glock front sights are secured with a roll pin. You’ll need a small, appropriately sized punch to drive the pin out.
Glock Sight Tool (if required): Some aftermarket sights come with specific installation tools. If your sights require one, ensure you have it.
Screwdriver (if required): Many front sights have screw that must be removed. Phillips head screwdrivers or Allen wrenches may be required.
Bench Vise (Optional): A bench vise can be extremely helpful, especially when using a punch and hammer. It provides a stable platform to secure the slide.
Gunsmithing Block or Padded Surface: This is crucial for protecting the slide from scratches. A gunsmithing block is ideal, but a piece of thick leather or a soft cloth will also work.
Cleaning Supplies: Before working on your Glock, make sure the area is clean. Gun cleaner and gun oil will be necessary.
New Glock Sights: Choose sights that fit your shooting needs. There are countless options, including:
Iron Sights: These are the most common type. They come in various configurations, including three-dot, two-dot, and blacked-out.
Tritium Sights: These sights use tritium vials that glow in low-light conditions.
Fiber Optic Sights: These sights utilize fiber optic rods that gather ambient light, providing a bright aiming point.
Adjustable Sights: Adjustable sights allow you to fine-tune the point of impact.
Red Dot Sights (RDS): These sights require slide modifications. They are quickly becoming the standard for many.
(Potentially) Thread Locker: If the manufacturer recommends it, have a small amount of Loctite or other thread locker on hand.
Removing the Old Sights: The Demolition Phase
With your tools and new sights ready, it’s time to remove the factory sights. Take your time, be deliberate, and pay close attention to detail.
Removing the rear sight requires either the sight pusher or the punch and hammer method.
The Rear Sight Removal Process
When utilizing a Glock sight pusher, insert the slide into the pusher, carefully aligning it with the pusher’s jaws. Make sure the slide is properly supported. Carefully adjust the sight pusher so that it pushes against the rear sight. Once everything is aligned, gradually apply pressure to the pusher, driving the rear sight out of its dovetail. Note the direction of movement. Typically, Glock rear sights are removed from left to right, but confirm this before proceeding. Avoid excessive force; if the sight is not moving easily, check the alignment and ensure the pusher is properly contacting the sight. Once the sight starts to move, continue to apply even pressure until it is fully dislodged.
If you do not have a sight pusher, use the punch and hammer technique.
Secure the slide in a padded vise or a gunsmithing block. Select the correct punch. Place the punch on the edge of the rear sight, and carefully tap the punch with the hammer. Ensure the punch is making direct contact with the sight and not the slide. Make slow and deliberate taps. The rear sight should start to move. Again, note the direction of movement. As with the sight pusher, proceed slowly and cautiously. If the sight is not moving after a few taps, check the alignment of the punch and hammer and increase the force very slightly. It is often helpful to apply a penetrating oil like Kroil or Liquid Wrench before attempting to move the sight, particularly if the sight is old.
Once the rear sight is removed, use a brush or cleaning solution to remove any remaining debris from the dovetail slot on the slide.
Now, let’s move on to the front sight.
Removing the Front Sight
The front sight removal process is usually simpler.
First, determine the type of front sight you have. The majority of front sights use either a screw or a roll pin.
If your front sight uses a screw, use the appropriate screwdriver to carefully unscrew it.
If the front sight utilizes a roll pin, place the slide on a padded surface. Position the small punch on the roll pin. Use the hammer to gently tap the punch until the roll pin is driven out. Ensure the punch is centered on the roll pin. Remove the old front sight.
Once the pin or screw is removed, the front sight can typically be pulled or tapped out from its dovetail. Again, the direction of movement will vary. Clean the front sight slot.
Installing the New Sights: The Reconstruction Phase
With the old sights removed, the installation of your new sights is next. Remember to keep the slide clean and free of debris.
Installing the Rear Sight
Clean the dovetail on the new rear sight before installation.
If you are using a sight pusher, center the new rear sight in the slide and align it. Once everything is aligned, use the sight pusher to press the sight into the dovetail slot. Make sure that the sight pusher is working correctly. Monitor the sight’s progress to ensure it goes in smoothly. As the sight is being pushed into place, pay attention to the sight picture to determine the correct alignment. If the sight is not moving easily, double-check the alignment and make certain the sight pusher is in the correct position. Adjust the sight until it is centered or in the desired position.
If you are using a punch and hammer to install the new rear sight, secure the slide in a padded vise or gunsmithing block. Align the new rear sight in the dovetail slot. Carefully tap the new rear sight into the dovetail slot with the punch and hammer. Go slowly, making small adjustments. Periodically check the alignment of the rear sight. Keep tapping with the hammer, until the sight is properly in place and secure.
(Optional) If the manufacturer recommends it, apply a small amount of thread locker.
Installing the Front Sight
Now, it’s time to replace the front sight.
If you have a screw-on front sight, align it with the slide and thread the screw in. Tighten the screw. Don’t over tighten.
If the front sight uses a roll pin, place the new front sight into position and insert the roll pin. Using the punch, tap the roll pin into place until it is flush.
Final Steps and Testing: The Evaluation Phase
Your sights are installed, but the process isn’t quite complete. A few final steps are necessary to ensure everything is working correctly.
Inspection
Inspect the sights to confirm that they are securely installed. Double-check alignment, and visually confirm that the sights are centered. You can do a quick alignment check with a ruler. Clean and lubricate the slide.
Function Check
Once you’ve installed the sights, rack the slide several times to ensure smooth operation. Check for any interference with the new sights. Make sure the slide cycles freely. This confirms the proper functionality of the gun.
Zeroing/Sighting In
Once you verify that the sights function correctly, you will need to test them on the range. Test fire the Glock to determine where the rounds are hitting. This will likely require adjustment. Explain how the new sights differ from your old sights. Adjust the sights as needed.
Range Test
The true test is at the range. With the gun unloaded and secured in its case, take your Glock to a safe shooting range. Place your target at your desired distance. Fire a few rounds to assess the point of impact. Adjust the sights as needed until the rounds are consistently hitting your point of aim. Be patient. It may take a few trips to the range to get your sights perfectly zeroed.
Troubleshooting and Common Issues
Despite careful planning, you may encounter some issues. Here are a few common challenges, with possible solutions:
Difficulty Removing the Old Sights: If the old sights are stubborn, a sight pusher is invaluable. Be patient. Apply penetrating oil. If using a punch and hammer, use a more substantial punch. If the sight is still stuck, and you don’t feel comfortable, consider taking the slide to a gunsmith.
Damaging the Slide: This is the most serious problem. The best way to avoid this is by using a sight pusher. Using the correct size punches. Always use a padded surface. Don’t force anything.
Sights Not Aligning Correctly: This is a common issue. Take your time and check for proper alignment. It might take a few attempts before you get it right.
Loose Sights After Installation: If the sights are loose, it may indicate a problem with the fit. If the manufacturer recommends it, use thread locker.
Conclusion
Changing the sights on a Glock is a straightforward process that can significantly enhance your shooting experience. By following these steps and prioritizing safety, you can confidently upgrade your Glock and enjoy improved accuracy and target acquisition. Remember that gun safety is paramount. If you are uncomfortable at any point in the process, seek professional assistance from a qualified gunsmith.
