TruGlo Tritium Night Sights for Glock 42/43/43X/48

Always Ready, Always Visible

When darkness falls, your sights shouldn't disappear with it. TruGlo's tritium night sights deliver the visibility you need in low-light conditions without requiring batteries or external charging.

How Tritium Works

These sights transition seamlessly from traditional white dot sights in daylight to glowing green dots when the lights go out. Tritium is a self-luminous material that requires no charging, no batteries, and no maintenance—it simply glows continuously for years.

Built for Reliability

• CNC-machined steel construction ensures durability and precision
• Green front and rear dots provide consistent sight picture in all lighting conditions
• Snag-resistant design prevents catching on clothing or holsters
• Standard holster compatible works with your existing gear
• Fits Glock 42, 43, 43X, and 48 (except MOS variants)

The Advantage

Unlike passive sights that fade in darkness, tritium sights maintain their visibility when you need it most. Whether you're training at night or preparing for self-defense in low-light scenarios, these sights keep your target acquisition sharp and your confidence high.

TruGlo uses the brightest tritium available, ensuring maximum visibility throughout the life of the sights.
