Ameriglo UC Tritium Night Sight Set for Glock 17-39 Gen 1-4 - Green Front with Orange Outline & Serrated U-Notch Rear

The AmeriGlo UC Tritium Night Sight Set for Glock 17-39 Gen 1-4 brings reliable low-light performance to your defensive handgun. Built around a green tritium front sight with an orange outline and a serrated U-notch rear, this sight set prioritizes rapid target acquisition and sight picture clarity—critical traits for a personal defense or concealed carry platform. The tritium illumination works passively in darkness, requiring no batteries or activation, making it an honest choice for shooters who want their sights to simply work when needed.

AmeriGlo designed these sights with the shooter's practical workflow in mind. The front sight's bright green tritium core and orange outline create a natural aiming reference that your eye gravitates to instinctively, even under stress. The serrated rear sight reduces glare and is shaped to assist one-hand slide manipulation—a tactical feature worth having if you ever need to reload or clear a malfunction single-handed. Both sights receive a case-hardened finish for durability and low-glare performance.

Compatibility is straightforward: these sights fit Glock Gen 1–4 models in 9mm, .40 S&W, and .380 ACP. They're also MOS-compatible if your slide is pre-cut for the mounting system. Installation is a straightforward, non-gunsmith job using standard Glock sight tools. Whether you're building a carry gun or upgrading an existing duty or range pistol, these tritium sights are a practical step toward better low-light readiness.

Frequently Asked Questions

Will these sights fit my Glock 17, 19, or other Gen 1–4 model?

Yes. The AmeriGlo UC set is engineered for Glock Gen 1–4 9mm, .40 S&W, and .380 ACP platforms. This includes the G17, G19, G22, G23, and G39. If your slide is MOS-cut for optics mounting, these sights are compatible with that system as well. Confirm your Glock generation before ordering; Gen 5 models require a different sight set.

How do tritium night sights work without batteries?

Tritium is a self-illuminating radioactive isotope sealed inside the sight tube. It emits a steady, low-level glow that is visible in darkness without any external power source or activation. The green front and rear tritium vials will glow for many years without maintenance, making them ideal for carry and defensive guns where reliability is non-negotiable.

What's the benefit of the orange outline on the front sight?

The orange outline (ProGlo) surrounds the green tritium core and provides a visual reference in daylight and low-light conditions. During the day, your eye sees and focuses on the orange outline; as light fades, the tritium becomes the dominant feature. This dual-mode design keeps your front sight usable and fast across a wide range of lighting conditions without switching to a backup sight.

Can I install these sights myself, or do I need a gunsmith?

Glock sights use a simple push-out, push-in design and do not require gunsmith intervention. Standard Glock sight tools are inexpensive and widely available. If you're uncomfortable with any firearms work, a gunsmith can install them in minutes at minimal cost.
