How to Install Night Sights on a Glock 19 Gen 5: Step-by-Step DIY Guide

If you’re searching for a Glock 19 Gen 5 night sights install guide, you’re likely a Glock owner looking to upgrade your handgun for better accuracy in low-light conditions. Whether you’re prepping for home defense, range use, or EDC (everyday carry), this DIY installation guide will walk you through the process safely and legally.

Why Upgrade to Night Sights on Your Glock 19 Gen 5?

Factory sights on many Glocks, including the Glock 19 Gen 5, are basic plastic options that work fine for daylight shooting—but lack visibility at night. Night sights, like Trijicon HD XR or AmeriGlo Spartan, glow in the dark and drastically improve target acquisition in low-light environments.

Benefits of Night Sights:

• Improved low-light targeting
• Faster target acquisition
• Greater shooting confidence in defensive situations
• Long-lasting tritium illumination (10+ years)

Tools You’ll Need for the Install

Before you begin, make sure you have the right tools:

• Night sight set (front and rear)
• Glock front sight tool or nut driver
• Rear sight pusher tool (or brass punch + hammer)
• Loctite (blue, medium strength)
• Nylon bench block or gun mat
• Microfiber cloth
• Safety glasses

🔧 Pro Tip: You can buy a complete Glock sight tool kit from sites like Brownells or MidwayUSA.

Step-by-Step Glock 19 Gen 5 Night Sight Installation

Step 1: Unload and Clear the Firearm

• Remove the magazine.
• Rack the slide to ensure there’s no round in the chamber.
• Double-check that the firearm is completely unloaded.

Step 2: Remove the Slide

• Pull the slide slightly back.
• Pull down on the takedown tabs.
• Let the slide move forward and remove it from the frame.

Step 3: Remove Factory Sights

• Use a Glock front sight tool to unscrew the front sight.
• For the rear sight, use a sight pusher or brass punch to gently drive it out from the dovetail.

Step 4: Install the New Front Sight

• Insert the new front sight post through the hole in the slide.
• Use a small drop of blue Loctite on the screw.
• Tighten it securely with your front sight tool.

Step 5: Install the Rear Sight

• Place the rear sight into the dovetail.
• Use a sight pusher tool to center it. Avoid using metal punches directly on the sight.
• Ensure it’s flush and aligned.

Step 6: Reassemble and Function Check

• Reassemble your Glock slide and frame.
• Perform a function check: rack the slide, dry fire (if safe), and inspect sight alignment.

FAQs on Glock Night Sight Installation

Can I install Glock night sights without a sight pusher? Yes, but using a brass punch and hammer requires care to avoid damage. A sight pusher tool is highly recommended for precision.

Do I need to zero the sights? Most quality sights are pre-zeroed. However, test fire your Glock at 7 and 15 yards to verify.

Will this void my warranty? Installing aftermarket sights does not void Glock’s warranty, but damage from improper installation may.

Final Thoughts: Is a DIY Glock Sight Install Worth It?

Absolutely. Learning how to install night sights on your Glock 19 Gen 5 not only saves money but also builds confidence in your firearm maintenance skills. With the right tools and careful steps, you’ll get professional-level results from your home workbench.

If you’re upgrading your Glock for tactical use, consider pairing your new night sights with a Streamlight TLR-1 HL weapon light for a complete low-light setup.

 Stay safe. Upgrade smart. Your Glock 19 Gen 5 deserves the best.
