If you've mounted a red dot on your Glock MOS slide, you need backup irons that won't block your optic's window—and that's exactly what the AmeriGlo Optics Compatible Tritium Handgun Sight Set delivers. This 1L tall sight set pairs a green tritium front sight with a flat black rear, giving you a cowitness picture that lets you aim through your optic while keeping steel sights ready if your electronics fail. The .220" front and .295" rear heights are engineered specifically for Glock MOS platforms, so they work seamlessly with popular compact optics like the Holosun 507K and 407K.
Built for shooters who demand reliability, these tritium sights glow in low light without batteries or charging—a genuine safety advantage on the range or in a defensive scenario. The green tritium front with black outline gives you quick target acquisition in daylight and maintains visibility in dim conditions. AmeriGlo's flat black rear is clean and snag-free, designed to complement your optic setup rather than compete with it.
The 1L height is the standard choice for most Glock MOS builds, but if you're running a particularly tall or short optic mount, AmeriGlo offers this same sight pattern in other heights. That modularity means you can dial in the exact cowitness you want. These are quality sights that won't rattle, won't fade, and will back up your optic when it matters.

Frequently Asked Questions
Will these sights work with my Glock MOS and red dot optic?
Yes. The AmeriGlo 1L tall set is engineered for Glock MOS slides and provides a cowitness sight picture with your mounted red dot. You can aim through the optic window while keeping these backup irons ready. They're compatible with compact optics like the Holosun 507K, 407K, EPS Carry, and Vortex Defender.
What does "1L tall" mean, and do I need a different height?
The 1L designation refers to the specific height: .220" front and .295" rear. AmeriGlo offers other heights (2L, 5L, XL, 2XL, 3XL, 5XL) if your optic mount stack requires taller or shorter sights for proper cowitness. The 1L is the standard choice for most Glock MOS builds.
Do the tritium sights need batteries or charging?
No. Tritium is a self-illuminating isotope that glows continuously in low light or darkness without batteries, charging, or external power. The green front sight will be visible in dim conditions indefinitely.
What's included in the sight set?
The set includes one green tritium front sight (.220" height) and one flat black rear sight (.295" height).
