The AmeriGlo GL305 i-Dot tritium sight set for Glock delivers fast, dependable aiming in low light and bright conditions alike. Built around a proven dot-over-dot sight picture, these night sights pair a green tritium front with an orange outline post for quick target acquisition, while the green tritium rear sight locks in vertical alignment with minimal thinking—exactly what you need when seconds matter at the range or in the field. The extended square-notch rear gives you a longer sight radius than standard Glock irons, boosting precision without requiring optics or a slide cut.
AmeriGlo engineered these sights for shooters who want better speed and accuracy from their carry or duty pistol. The glare-reducing undercut on the rear sight face keeps light from washing out your sight picture, and the contrast between the green tritium elements and the orange front outline makes target focus intuitive—whether you're shooting in daylight or after dark. Installation is straightforward on most Glock models, making this a practical upgrade over factory plastic sights.
If you're serious about your Glock's performance, tritium night sights are one of the smartest upgrades you can make. They run for years without batteries, they don't snag on clothing, and they let you shoot accurately when factory sights leave you guessing. The GL305 set brings that reliability and speed to your training and carry gun.

Frequently Asked Questions
Will the AmeriGlo GL305 sights work on my Glock?
These sights are designed for Glock pistols. Confirm your specific model is compatible before ordering, as Glock dimensions vary across generations and frame sizes.
How long do tritium sights stay bright?
Tritium vials have a half-life of approximately 12.5 years, meaning they emit useful light for roughly that period without any battery or charging required. Brightness fades gradually over time.
What's the advantage of the dot-over-dot sight picture?
The dot-over-dot configuration lets you align the front post dot in the center of the rear sight notch quickly and consistently. This speeds up your sight acquisition and helps with shooting accuracy, especially under stress or in dim light.
Can I use these sights for both daytime and low-light shooting?
Yes. The green tritium glows in darkness, while the orange outline on the front sight provides contrast and focus in daylight. The extended rear sight radius also improves precision in all lighting conditions.
