Meprolight Tru-Dot Tritium Night Sights Green Sig Sauer P-Series

The Meprolight Tru-Dot Sight Set delivers reliable target acquisition in complete darkness through self-illuminated tritium inserts. This professional-grade sight system transforms any Sig Sauer P-Series pistol into a 24/7 defensive tool without batteries or external light sources.

What Makes This Different

Unlike fiber optic sights that fail in darkness or basic white dot sights that disappear at dusk, the Tru-Dot system uses gaseous tritium vials that glow continuously for 12+ years. The three-dot configuration provides instant sight alignment through muscle memory, while the green tritium offers optimal visibility to the human eye in low-light conditions. Swiss-made tritium vials maintain consistent brightness output rated at 25 millicuries per vial.

Key Features

• Self-illuminated green tritium front and rear sight dots for 24/7 visibility
• Machined steel construction with corrosion-resistant coating
• Direct replacement for factory Sig Sauer P-Series sights
• Three-dot sight picture for rapid target acquisition
• 12-year tritium half-life with no battery requirements
• Snag-resistant low-profile design for concealed carry
• White outline rings around tritium vials for daylight use

Field testing demonstrates consistent point-of-impact accuracy across temperature ranges from -40°F to 140°F. The sight set maintains zero through thousands of rounds in duty and competition environments. Law enforcement agencies rely on tritium sights for patrol and tactical operations where lighting conditions change rapidly. The robust steel construction withstands holster wear and environmental exposure without losing tritium brightness.
