The Glock 23 is one of the premiere self-defense pistols. The everyday Joe who’s carrying concealed, the 23 are awesome compromises of comfort and power. There isn’t much one needs to change on the Glock 23 but the sights are one of them. A good set of night sights opens the world up for the shooter. Why? Regardless of light limitations, you can always engage your target.

Night sights shouldn’t limit a shooter during the day and the sights should still be fast and easy to acquire. Night sights should glow nice and bright. If you are swapping Glock’s plastic sights and spending a bit of money you should choose metal as well. Metal sights are a lot tougher and much more dependable. Here are the 4 best night sights for Glock 23 pistols:

Ameriglo Ghost Ring

This unusual set of sights looks something more akin to aperture sights found on long guns. These are not common pistol sights, but they have been proven to be highly effective as night sights, and they also perform well during the day. These sights excel for those who may have decreased vision and are forced to wear glasses.

The sights feature a rear ring and a front post. Inserted on the left and right side of the rear sight ring are glowing tritium inserts. The front sight features a tritium inserted in the middle of the post, surrounded by a bright white paint. The paint does not glow and is designed to be used during the day when the tritium inserts are not glowing. At night, the sights appear as traditional three-dot variety, and during the day the ring itself is used.

The sights themselves are very easy to acquire, and allow for rapid engagement, perfect for self-defense, which is one of the main uses of the Glock 23. The Ameriglo Ghost ring sights are assembled from steel and are tough as nails. The rear sight is serrated to reduce glare from ambient light. The tritium inserts glow brightly and are incredibly easy to acquire in the dark. These are among the best night sights for Glock 23 period.

Trijicon HD GL101O

Trijicon is one of the world’s best sight makers, producing sights for everything from sniper rifles to the industrious Glock 23 handgun. Their sights are known to be rock solid—optics and sights you can count on in a fight. The bright and tough sights make a large claim with just their name, and they back it up. These all-metal sights are tough enough to last in the harshest non-permissive environments.

The Trijicon HD GL101O sights use tritium inserts that are capped with a sapphire jewel. Tritium is an extremely bright substance that glows for years before it even begins to dim. The sapphire cap and the use of protective aluminum cylinders protect the tritium inserts from both the recoil of the snappy .40 Smith and Wesson cartridge and the harshest of cleaning solvents.

The Trijicon night sights are incredibly bright in the dark: their glow is ridiculously easy to see. The inserts are surrounded by a bright white ring that is designed to be used during the day, making these sights an excellent option for a self-defense pistol like the Glock 23.

These Truglo night sights will fit in with any standard Glock 23 holster without modification.

Installation is very easy to do, but if you’re not sure the best bet would be to see a gunsmith. The installation only takes a few minutes and a sight tool is required. This Truglo is among the best night sights for Glock 23 if you’re a budget shooter.
