The TruGlo TG231N1 tritium night sights deliver reliable low-light visibility for 1911-platform handguns, whether you're working in dim indoor ranges, low-light hunting scenarios, or defensive carry situations. Built with CNC-machined steel and filled with the brightest tritium available, these green front and rear sights glow without batteries or charging—they're always ready when conditions demand illumination. The snag-resistant design won't catch on holsters or gear during draws, and the compact profile fits standard holster fitment seamlessly.
Designed specifically for 1911 pistols with Novak LoMount dovetail cuts—including Ruger SR1911 models in any barrel length—these sights offer the traditional fixed-sight reliability that serious shooters trust. The green tritium tubes paired with a standard front post and rear notch create a sight picture that's fast to acquire in darkness while remaining precise enough for deliberate fire. Whether you carry daily or reserve your 1911 for specialized shooting, upgrading to tritium sights eliminates the need to remember to charge glow-in-the-dark alternatives.
Installation into your existing Novak LoMount cuts requires a competent gunsmith—slide fitting may be needed—so plan accordingly. Once installed, these sights will serve you for years without maintenance, functioning in any weather or light condition your shooting demands.
