The TRUGLO TFO Glock Sight Set brings a proven two-technology approach to fast, reliable target acquisition on your Glock Gen 1–5 models 17–39. Day or night, you need your sights bright and instinctive—and that's where tritium fiber-optic sights shine. By combining tritium night-light technology with fiber-optic light-gathering, these steel sights stay visible in glaring sunlight, low light, and complete darkness without batteries or adjustment. Whether you're training at the range, responding in a home-defense scenario, or carrying professionally, consistent sight picture is non-negotiable.
TFO sights have been a trusted choice among shooters for years because they solve a real problem: traditional iron sights fade in bright conditions, while pure tritium can be dim in daylight. This hybrid design uses a green fiber-optic front sight and yellow fiber-optic rear sight to capture ambient light, while the tritium element takes over when that light disappears. The result is a bright, intuitive sight picture across any lighting condition. The steel construction is built to handle the abuse of duty carry or frequent training, and the design works with your existing holsters without modification.
Installation is straightforward on compatible Glock pistols, and the sight geometry is proven by thousands of users in the field. If you shoot a Glock and want sights that work equally well at the 3 a.m. security check and the noon-day range trip, TFO is a practical, time-tested upgrade.
