Night Fision Tritium Night Sights for Glock 20/21

Night Fision has reimagined the tritium night sight with a patented injection-molded design that outperforms traditional aluminum-sleeved alternatives. Rather than relying on painted-on white rings, Night Fision's proprietary construction creates what they call "The Perfect Dot"—a brighter, more durable aiming reference that works equally well in daylight and darkness.

Key Features

• Tritium Technology: Green tritium vials provide reliable low-light visibility without batteries or charging
• Glow Dome Front Sight: Phosphorescent material on the front sight aids acquisition as your eyes adjust to darkness
• Durable Construction: Injection-molded sleeves securely hold tritium vials and resist damage from regular handling and shooting
• The Perfect Dot: Bright, injection-molded ring design offers superior visibility compared to painted alternatives

Specifications

• Front sight width: 0.14"
• Front sight height: 0.213"
• Rear sight height: 0.272"
• Color: Green tritium with yellow front outline and white rear outline
• Fits: Glock 20, 21, 29, 30, 36, 40, 41 (including S and SF variants)

Why Choose Night Fision
