Meprolight Tru-Dot Tritium Night Sights for Kahr K/P/MK/PM Series

The Meprolight USA 151203101 Tru-Dot sight set transforms target acquisition in low-light conditions with self-illuminated tritium technology. This front and rear sight combination delivers consistent visibility without batteries or external light sources for up to 12 years.

What Makes This Different

Unlike standard iron sights that become invisible in darkness, the Tru-Dot system uses tritium gas capsules sealed in borosilicate glass to create a constant green glow. The white outline surrounding each tritium dot provides enhanced contrast in daylight conditions. This dual-illumination approach maintains sight picture clarity across all lighting environments, from bright sunlight to complete darkness.

Key Features

• Self-luminous green tritium inserts rated for 12+ years of continuous illumination
• White outline rings enhance daylight visibility and target contrast
• Precision-machined steel construction with corrosion-resistant finish
• Direct replacement for factory sights on Kahr K, P, MK, and PM series pistols
• Low-profile design maintains holster compatibility
• No batteries or maintenance required for tritium operation
• Shock-resistant borosilicate glass protects tritium capsules

Field testing demonstrates reliable performance across temperature extremes from -40°F to 160°F. The sight set maintains zero through thousands of rounds while providing instant target acquisition in tactical situations. Law enforcement agencies specify similar tritium configurations for duty weapons due to their consistent performance in varying light conditions. The green tritium wavelength offers optimal visibility to the human eye while preserving night vision adaptation.
