Trijicon DI Night Sight Set for Glock 42/43/43X/48

Trijicon DI Night Sights: Daylight Brightness Meets Low-Light Performance

The Trijicon DI Night Sight Set represents a significant advancement in aiming solutions for compact Glock pistols. These dual-illuminated sights deliver the best of both worlds: fiber optic brightness in daylight and tritium reliability when darkness falls.

How They Work

Trijicon's patented dual-illumination technology combines:

• Fiber optic front sight with green tritium lamp, capped with a sapphire jewel for durability
• Green tritium rear sight for a constant aiming point in complete darkness
• Chemical and heat-resistant fiber finished using the same proprietary technique as Trijicon's legendary ACOG optics

This combination ensures an ultra-bright aiming point across all lighting conditions—from bright daylight to low-light environments to complete darkness.

Field-Configurable Design

Unlike traditional night sights, the DI features an industry-first interchangeable fiber design. You can:

• Replace the fiber in the field without special tools
• Choose from multiple fiber and ring retainer colors to personalize your aiming solution
• Adapt your sights to your preferences and shooting conditions

What's Included

• Front and rear night sight set with green tritium and black outline
• Two green fiber replacement pieces for field maintenance
• T10 torque L-key for installation and adjustment

Compatibility

Fits Glock Models 42, 43, 43X, and 48 (standard models only; excludes MOS variants).

These sights are ideal for shooters who demand reliability across all lighting conditions and appreciate the flexibility to customize their sight picture.
