The TruGlo TG231MP4W Tritium Pro night sights transform low-light shooting accuracy with self-illuminating tritium technology. These precision-machined steel sights eliminate the guesswork in dim conditions where standard sights fail. Built specifically for Smith & Wesson M&P Shield pistols, they deliver consistent sight picture regardless of ambient lighting.
What Makes This Different
Unlike basic tritium sights that fade over time, the Tritium Pro series maintains brightness for 12+ years through Swiss tritium vials. The front sight combines green tritium with a white outline ring for rapid target acquisition, while the rear sight features dual green tritium dots for perfect alignment. This three-dot configuration provides faster sight acquisition than single-dot systems while maintaining precision accuracy.
Key Features
- Swiss tritium vials rated for 12+ years of consistent illumination
- CNC-machined steel construction with protective coating resists impact and corrosion
- White outline front sight ring enhances visibility in daylight conditions
- Three-dot configuration (front white/green, rear dual green) for rapid alignment
- Drop-in replacement for factory M&P Shield sights - no gunsmith required
- Snag-resistant profile maintains smooth draw from concealment holsters
- Angled rear sight face enables emergency one-handed slide manipulation
Field performance proves reliable across temperature extremes from -20°F to 150°F without brightness degradation. The tritium maintains visibility in complete darkness while the white outline ensures daylight accuracy. Law enforcement agencies report improved qualification scores during low-light training scenarios. The steel construction withstands repeated holster draw cycles and accidental impacts that would damage polymer alternatives.
