AmeriGlo SG161 Tritium Night Sights for Sig Sauer P320 P365

The AmeriGlo SG161 Classic Tritium Sight Set transforms low-light shooting accuracy for Sig Sauer pistols. These professional-grade night sights feature self-luminous tritium inserts that glow consistently for 12+ years without batteries or external light sources.

What Makes This Different

Unlike basic white dot sights, the SG161 combines tritium illumination with high-contrast white outlines for rapid target acquisition in any lighting condition. The Classic configuration provides a traditional sight picture with equal-height front and rear dots. Swiss-made tritium vials maintain consistent brightness output rated at 25% intensity after 12 years, significantly outperforming cheaper alternatives that fade within 5-7 years.

Key Features

• Self-luminous green tritium inserts with 12+ year lifespan
• White outline rings for enhanced daylight visibility and contrast

Field testing demonstrates consistent point-of-impact accuracy across temperature ranges from -20°F to 140°F. The nitride finish resists corrosion and wear from daily carry, while the steel construction withstands repeated slide cycling and holster draw cycles. Law enforcement agencies specify these sights for duty weapons due to their reliability in critical situations.
