The TruGlo TG231X Tritium night sights deliver reliable low-light target acquisition with self-illuminating tritium inserts that require no batteries or external light source. These precision-machined sights maintain visibility in complete darkness for up to 12 years through Swiss tritium gas technology.
What Makes This Different
Unlike fiber optic sights that fade in darkness, the TG231X features genuine tritium gas capsules that glow continuously without degradation from weather exposure. The green tritium front sight provides high contrast against most backgrounds, while the matching rear sight creates consistent sight alignment. CNC-machined from steel construction ensures the sights maintain zero even under heavy recoil and repeated holster draw cycles.Key Features
