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

Superior Sight Picture in Any Light

TruGlo's TFO (Tritium Fiber-Optic) sights represent the pinnacle of handgun sight design. By pairing fiber-optic technology with tritium night sights, these sights deliver a bright, reliable sight picture whether you're shooting in brilliant daylight or complete darkness.

Key Features

• Patented TFO Technology: Combines the best of fiber-optics and tritium for unmatched brightness transitions
• Day/Night Performance: Fiber-optic elements gather ambient light for daytime brightness; tritium glows independently in darkness
• No Batteries Required: Tritium is self-illuminating and requires no external power
• CNC-Machined Steel Construction: Durable, precision-engineered for reliable performance
• Concealed Fiber Design: Fiber-optic elements are hidden from the target's view
• Snag-Resistant Profile: Designed to work smoothly with standard holsters
• Green Sight Configuration: Both front and rear sights feature green tritium and fiber-optic elements

Compatibility

These sights fit Glock 42, 43, 43X, and 48 models (excludes M.O.S. variants).

Why TFO Sights Matter

When accuracy counts, your sights must perform. TruGlo's decades of experience in fiber-optic technology combined with proven tritium night sight design creates a sight system that works reliably across all shooting conditions—from early morning to dusk and everything in between.
