TruGlo TFO TG131ST2Y Tritium Fiber Optic Sights Sig P-Series

The TruGlo TFO TG131ST2Y sight set delivers 24-hour visibility through its innovative tritium and fiber optic combination technology. This sight system provides bright daylight performance from fiber optics while maintaining low-light visibility through self-illuminating tritium inserts. Designed specifically for Sig Sauer P-Series pistols, these sights offer reliable target acquisition in any lighting condition.

What Makes This Different

TFO (Tritium Fiber Optic) technology combines two proven sight systems into one reliable package. While standard night sights rely solely on tritium and basic fiber optic sights work only in adequate light, TFO sights automatically adapt to lighting conditions. The green front sight provides maximum contrast against most backgrounds, while the yellow rear sight creates proper sight alignment without confusion.

Key Features

• Tritium and fiber optic combination provides 24-hour sight visibility
• Green tritium/fiber optic front sight for enhanced target contrast
• Yellow tritium/fiber optic rear sight prevents front/rear confusion
• CNC-machined steel construction with protective sight ring
• Fits Sig Sauer P-Series pistols with #6 front and #8 rear dovetails
• Swiss tritium vials rated for 12-year brightness guarantee
• Snag-resistant profile maintains holster compatibility

These sights excel in competitive shooting where rapid target acquisition matters, law enforcement applications requiring reliable performance, and personal defense scenarios with varying light conditions. The steel construction withstands repeated holstering and environmental exposure. Installation requires standard sight pusher tools and proper torque specifications for secure mounting.
