HiViz GPN301 LiteWave H3 Tritium Front Sight Ruger GP100 Green

The HiViz GPN301 LiteWave H3 Front Sight transforms target acquisition on Ruger GP100 revolvers with its tritium-powered illumination system. This drop-in replacement sight combines self-luminous tritium with a bright white outline ring for enhanced visibility across all lighting conditions. Professional gunsmiths and competitive shooters recognize the LiteWave H3 series for delivering consistent sight picture reliability when standard factory sights fall short.

What Makes This Different

Unlike basic fiber optic sights that depend on ambient light, the GPN301 incorporates genuine Swiss tritium that glows continuously for over 12 years without batteries or external light sources. The white outline ring creates a sharp contrast against dark targets while the green tritium center provides a precise aiming point in low-light scenarios. Standard factory sights often become invisible in dawn, dusk, or indoor conditions where this tritium sight maintains full visibility.

Key Features

• Self-luminous green tritium insert rated for 12+ year lifespan
• Bright white outline ring enhances target contrast and sight alignment
• Direct replacement for factory Ruger GP100 front sight - no modifications required
• CNC-machined steel construction with corrosion-resistant finish
• Low-profile design maintains holster compatibility
• Precision-regulated tritium meets ISO standards for consistent brightness
• Impact-resistant housing protects tritium vial from recoil damage

Range testing demonstrates the GPN301's ability to maintain sight picture consistency across varying light conditions, from bright outdoor ranges to dimly lit indoor facilities. Competition shooters report faster target transitions during timed fire stages, while law enforcement officers appreciate the reliable visibility during low-light tactical scenarios. The tritium remains visible without compromising night vision adaptation, making it suitable for home defense applications where preserving dark-adapted vision proves critical.
