Safety First: Your Top Priority
Treat Every Firearm as if It’s Loaded
Always assume your Glock is loaded, even if you think it’s not. This mindset promotes a consistent and safe approach.
Control the Muzzle
Always point the muzzle in a safe direction, ideally downrange in a location where an accidental discharge would not cause injury or property damage.
Keep Your Finger Off the Trigger
Unless you are ready to shoot, keep your finger off the trigger and outside the trigger guard.
Be Sure of Your Target and What’s Beyond It
Always identify your target and be aware of what is behind it before pulling the trigger.
Unload and Verify
The most critical step. Remove the magazine from the Glock. Next, visually inspect the chamber to ensure it’s empty. Run your finger or a cleaning rod through the chamber to ensure no rounds are present. Finally, lock the slide back, physically inspect the chamber again, and feel it to confirm it is empty.
Safe Direction
Make sure your Glock is pointed in a safe direction throughout the entire process.
Clear the Workspace
Ensure your workspace is clear of any ammunition. Remove any live rounds from the area to prevent accidental discharge during the sight-changing process.
Eye Protection
Wear appropriate eye protection throughout the entire process to protect your eyes from any flying debris.
Focused Environment
Choose a well-lit, clean, and organized workspace free from distractions. This helps you focus on the task at hand and prevents potential errors.
Gathering the Right Gear: The Tools of the Trade
Sight Pusher Tool
This is the preferred method. Sight pushers are designed to press the sights out and install new ones. They are far less likely to damage your slide or the sights compared to using a punch and hammer. Many sight pushers are universal and can accommodate various sight configurations. There are also models specifically designed for Glock pistols. Select a sight pusher that is appropriate for your sight profile. Research your options.
Bench Block or Vise
A stable platform is necessary to secure the slide during the process. A bench block provides a surface to support the slide, while a vise firmly holds it in place. Ensure your vise has padded jaws or jaw covers to prevent scratching your slide.
Vice with Padded Jaw
A bench vise provides a secure way to hold the slide in place while applying force. Make sure the vise jaws are lined with soft materials or use jaw covers to avoid damaging your slide.
Brass or Nylon Punches
If you choose not to use a sight pusher, punches are necessary to drive the sights out. Brass or nylon punches are preferred over steel, as they are less likely to mar the finish on your slide or damage the sights. Have a variety of punch sizes available.
Gunsmith Hammer
A small hammer, such as a gunsmith hammer, is ideal for tapping punches or for use with the sight pusher. Avoid using a large, heavy hammer, as it increases the risk of applying too much force.
Gun Grease or Oil
Lubrication is essential during the installation process. Use a quality gun grease or oil to lightly lubricate the dovetail cuts on your slide. This will ease the installation of the new sights and help prevent corrosion.
Non-Marring Tools (Optional)
Consider using non-marring tools, such as nylon wedges or plastic tools, to help protect your slide and sights from scratches during the installation or removal.
Preparing for Success: Step-by-Step Instructions
Removing the Existing Sights
Secure the Slide
Place the slide into a padded vise or use a bench block, ensuring it is securely positioned. If using a vise, pad the jaws to protect the finish.
Using a Sight Pusher
Position the slide securely. Align the sight pusher to the rear sight.
Gradually tighten the sight pusher, applying even pressure to push the sight out.
Continue turning the pusher until the rear sight is fully removed.
Repeat the procedure for the front sight, if using a sight pusher for it.
Using a Punch and Hammer
Identify the Direction: Glock sights are typically drifted out from left to right. Check for any markings or indications on the sights to confirm the correct direction.
Position the punch squarely against the side of the rear sight.
Tap the punch gently with your hammer, starting with light taps and gradually increasing the force as needed. Go slowly and consistently. Be careful not to bend the slide or the punch.
Continue tapping until the rear sight starts to move.
Once the sight begins to move, continue tapping until it’s completely removed.
Repeat the process for the front sight, ensuring it is drifted out in the proper direction.
Front Sight Removal
Front sight removal often involves removing a small screw. Use the proper screwdriver to remove this screw, and the front sight should come free.
Preparing the Slide (Optional but Recommended)
Use a cleaning solvent to wipe down the dovetail cuts on your slide. This removes any dirt or debris and ensures a clean surface for the new sights.
Installing the New Sights
Lubrication is Key
Apply a small amount of gun grease or oil to the dovetail cuts on the slide. This will ease the installation process and prevent friction, reducing the chance of damaging your slide or the new sights.
Rear Sight Installation
Using a Sight Pusher: Using a sight pusher will provide the most secure and reliable method for installing new sights. Position the slide, align the pusher, and gradually tighten it until the rear sight is properly seated.
Using a Punch and Hammer (Alternative): If using a punch and hammer, align the new rear sight with the dovetail cut. Place the punch against the sight and tap gently with your hammer to start the sight into place.
Gradually drive the new rear sight into the dovetail cut, checking for alignment as you go. Be careful not to over-tighten the sight, as this could damage it. Make sure the sight is centered.
Front Sight Installation
Follow the specific instructions for your front sight type. This often involves:
Inserting the new front sight into the designated opening.
Tightening the screw or screws to secure the front sight.
Apply Loctite (Blue Loctite is recommended) to the threads of the front sight screw to prevent loosening.
Tighten the screw to the manufacturer’s recommended torque specification (if applicable).
Final Adjustments and Centering
Once both sights are installed, inspect them to ensure they are properly aligned.
You may need to make minor adjustments to center the sights.
Essential Tips and Things to Keep in Mind
Drift Direction is Critical
Glock sights are typically installed from left to right and removed from right to left. Always confirm the correct drift direction on your specific Glock model.
Choose Quality Tools
Avoid using low-quality tools, as they can damage your slide or the new sights. Invest in high-quality tools that are designed for gunsmithing.
Patience is a Virtue
Take your time throughout the process. Rushing can lead to mistakes and potential damage.
Proper Screw Tightening
If your sights use screws, ensure they are tightened to the manufacturer’s recommended torque specifications. Apply thread locker (like blue Loctite) to prevent loosening.
Professional Guidance
If you’re unsure about any step or are uncomfortable with the process, consult a qualified gunsmith. They have the expertise and tools to safely install your new sights.
Sight Alignment and Zeroing
After installing your new sights, you’ll need to check the sight alignment and potentially zero your firearm. This involves ensuring your sights are properly aligned with the target and adjusting them if necessary. Consult your Glock owner’s manual or a qualified gunsmith for instructions on how to zero your Glock.
Wrapping It Up: Final Thoughts
Changing the sights on your Glock can significantly enhance your shooting experience. By following the steps outlined above, you can confidently upgrade your Glock’s sights and enjoy improved accuracy, a customized appearance, and potentially increased performance. Remember, safety is paramount. Take your time, use the right tools, and enjoy the process.
