Trijicon Bright & Tough Night Sights Green Tritium Glock 20/21

The Trijicon 600227 Bright & Tough Night Sights deliver reliable target acquisition in complete darkness through self-illuminating tritium inserts. These precision-machined steel sights feature green tritium lamps with white outline rings for enhanced visibility across all lighting conditions.

What Makes This Different

Unlike standard factory sights that become invisible in low light, these tritium night sights maintain constant illumination for 12+ years without batteries or external power sources. The machined steel construction withstands heavy recoil and impact better than polymer alternatives. White outline rings around the tritium inserts create a clear sight picture during daylight hours while the tritium glows bright green in darkness.

Key Features

• Self-luminous green tritium inserts provide 12+ year lifespan
• White outline rings enhance daylight visibility and sight alignment
• Machined steel construction handles magnum recoil from 10mm and .45 ACP
• Factory-specific fit for Glock 20 and 21 large frame pistols
• Three-dot sight configuration for fast target acquisition

• Maintains zero through temperature extremes and heavy use

These sights excel in tactical applications where split-second target identification matters. Law enforcement officers rely on the consistent tritium glow during building searches and vehicle stops. The robust construction handles the punishment of daily carry and training sessions. Competition shooters appreciate the precise sight picture for rapid target transitions in low-light stages.
