TruGlo TFO Tritium/Fiber Optic Sights for Glock 42/43

Superior Sight Picture in Any Condition

TruGlo's TFO (Tritium Fiber Optic) sights represent a genuine advancement in handgun sight technology. By pairing fiber-optic brightness with tritium night sight capability, these sights deliver a consistently bright, reliable sight picture whether you're shooting in bright daylight or complete darkness.

How TFO Technology Works

The system uses a patented combination of two proven technologies:

• Fiber-optic front sight gathers ambient light to produce exceptional brightness in daylight conditions
• Tritium rear sight glows without batteries, providing visibility in low-light and darkness
• No batteries required—the tritium works indefinitely
• The concealed fiber-optic design prevents target interference

Built for Duty

• CNC-machined steel construction for durability and precision
• Snag-resistant design fits standard holsters without modification
• Green front sight with yellow rear sight for rapid target acquisition
• Unbelievable light-condition transitions from bright sun to complete darkness

Compatibility

Fits Glock 42, 43, 43X, and 48 (standard models; excludes M.O.S. variants).

When accuracy matters, sight brightness counts. TFO sights ensure you can see your sights clearly whenever you need to shoot.
