The Ameriglo I-Dot sight set for Glock 42, 43, 43X, and 48 brings trusted night-sight technology to compact and subcompact pistols in a package designed for quick, intuitive aiming in any light. Built around a dot-over-dot sight picture, the I-Dot configuration aligns vertically in a way that feels natural to shooters transitioning between daylight and low-light scenarios. Whether you're carrying daily, training at the range, or preparing for defensive situations, these tritium sights deliver fast target acquisition without the learning curve of more complex reticle designs.
AmeriGlo has engineered the I-Dot to work across Glock's slim-line lineup, including Glock MOS variants for shooters who've already added an optic mount. The green tritium front sight features an orange outline that creates a bright, visible aiming point under any conditions, while the rear sight's square notch gives you a clean sight picture whether you're shooting in broad daylight or relying entirely on that tritium glow. Case-hardened finish on both front and rear sights resists wear and corrosion—important for a pistol that's likely to see regular carry or use.
Installation is straightforward on compatible Glock frames, and the compact profile keeps your profile low and snag-free when drawing from concealment. The dot-over-dot geometry means less transition time if you're used to standard three-dot sights; your eye finds the center quickly and stays there.

Frequently Asked Questions
Will these sights work on my Glock 43X with a red dot mount?
Yes—the Ameriglo I-Dot set is compatible with Glock MOS (Modular Optics System) slides on the 43X and other compatible models, so you can run both iron sights and an optic simultaneously.
What's the advantage of the dot-over-dot sight picture?
The dot-over-dot design simplifies vertical sight alignment. Your eye naturally centers the smaller front dot within the rear aperture, cutting down on sight picture confusion compared to traditional three-dot or post-and-notch designs, especially under stress or in low light.
Are these sights suitable for concealed carry?
Yes. The compact profile and low sight height make them ideal for carry guns. The case-hardened finish resists snagging and corrosion from daily draw and holster work.
Will these tritium sights glow in complete darkness?
Tritium sights are self-illuminated and will be visible in low-light and no-light conditions without relying on a flashlight or ambient light, though brightness diminishes with age. The green tritium combined with the orange outline also provides a clear sight picture in daylight without glare.
