TRUGLO Tritium X Night Sight Set for Glock Handguns - Bright 3-Dot

In this review the TRUGLO Tritium X Night Sight Set is evaluated for shooters who want a reliable, bright sight upgrade for Glock 42, 43/43X and 48 models. The bottom line: this set is for owners who need constant low-light visibility without batteries and a compact, snag-free profile that fits most standard holsters. Installation is straightforward and the sights transition from visible white dots in daylight to vivid green tritium dots in the dark, making them the single biggest reason to choose these sights over basic factory options.

Key Features

• Glowing Night Sights: Swiss tritium lamps provide a steady glow in low light and complete darkness so you do not need batteries or an external light source.
• 3-Dot Configuration: The familiar three-dot layout preserves a quick sight picture for fast target acquisition in both day and night conditions.
• Durable Steel Construction: Solid steel bodies with a Fortress nitride finish resist wear and corrosion to match the durability expected from a carry handgun.
• Front Focus-Lock Ring: A white ring around the front sight improves visual contrast and speeds alignment for improved accuracy.
• Snag-Free Design: Compact, nitride-coated sights with serrations reduce glare and are shaped to fit most standard holsters without catching.

Who It's For

The TRUGLO Tritium X set is aimed at concealed carry owners and range shooters who want unparalleled visibility in low light without relying on electronics. It suits Glock 42, 43/43X and 48 users who want a direct swap for their stock sights and prioritize a clean sight picture and snag-resistant shape.

Those looking for sights for MOS slide models or owners of other handgun families should look elsewhere, and shooters who prefer fiber optic or fully white daytime-only sights may prefer alternatives. It is not a universal sight; compatibility is specific to the stated Glock subcompact models.
