How to Replace Your Factory Iron Sights (Fast & Easy)

Introduction

In this tutorial, you'll learn how to replace the factory iron sights on your Glock 19 with new night sights from TR glow. This process is straightforward and can be done at home with the right tools. By following these steps, you'll enhance your firearm's accuracy and visibility in low-light conditions.

Step 1: Ensure Safety

• Always start by ensuring your firearm is unloaded.
• Remove any ammunition or loaded magazines from your workspace.
• Visually inspect the chamber and pull the trigger in a safe direction to confirm the gun is empty.

Step 2: Disassemble the Glock

• Remove the slide from the frame:
  • Pull back the slide slightly (about a quarter inch).
  • Depress the slide lock (takedown lever) with your thumb and forefinger.
  • Walk the slide off the frame while maintaining control.
• Remove the guide rod and barrel:
  • Turn the slide upside down.
  • Lift out the guide rod and then the barrel.

Step 3: Remove the Front Sight

• Locate the flathead screw securing the front sight. Use a specialized tool to access it:
  • Use the multi-purpose tool that includes a front sight tool with a magnetic tip to capture the screw.
• Unscrew the flathead screw and carefully remove it. The front sight should now come out easily.
• Observe the shape of the sight hole; it is oval, ensuring the new sight can only fit one way.

Step 4: Install the New Front Sight

• Take the new front sight and insert it into the oval hole, ensuring it’s aligned properly.
• Use the magnetic tip of your tool to hold the screw while you insert it back into the sight.
• Apply a small amount of Loctite to the screw threads (not into the hole) to prevent it from loosening over time.
• Tighten the screw until it is fingertight. Avoid over-tightening to prevent stripping.

Step 5: Remove the Rear Sight

• The rear sight may be more challenging to remove. Use a sight pusher tool to avoid damaging it:
  • Insert the slide into the sight pusher and ensure it is properly secured.
  • Adjust the tool to ensure it is positioned correctly over the rear sight.
• Push the rear sight out; it should come out smoothly without damage.

Step 6: Install the New Rear Sight

• Take the new rear sight and align it in the dovetail.
• If it does not slide in easily, use the sight pusher or a nylon-tipped hammer to tap it into place gently.
• Ensure it is centered and aligned.
• Tighten the set screw on the rear sight with an Allen wrench, applying a small amount of Loctite as needed.

Conclusion

Replacing the factory iron sights on your Glock 19 is a manageable task that can greatly enhance your shooting experience. Ensure you have the right tools, particularly the front sight tool and sight pusher, for an easier installation. With these new sights, you'll improve your accuracy and visibility, especially in low-light conditions. Happy shooting!
