The AmeriGlo I-Dot tritium night sight set delivers fast, reliable aiming for your Glock Gen 1-4 pistol in any light. These night sights use a proven dot-over-dot configuration: a green tritium dot up front circled by an orange outline, paired with a single green dot in the rear. The result is an intuitive vertical sight picture that your eyes naturally stack, cutting seconds off target acquisition when it matters most.
Tritium night sights glow continuously without batteries, powered by self-luminous gas tubes that stay bright for years. Whether you're running defensive drills at dusk, standing night watch, or just making sure your gun is ready after dark, these sights work without thinking. The case-hardened finish protects against the scratches and dings of carry and training, holding zero through real use.
Installation is a straightforward swap if you have armorer skills; if not, a qualified gunsmith will have you done in minutes. These fit Glock Gen 1-4 frames in 9mm, .40 S&W, and .380 ACP—verify your slide isn't MOS-cut, as these sights require standard dovetail mounting. Once mounted, you get a complete front and rear sight set, so no hunting for parts.

Frequently Asked Questions
Will these fit my Glock Gen 5?
No, this set is designed for Glock Gen 1-4 pistols. Gen 5 frames have different slide dimensions and require sights specifically machined for that generation.
Can I install these myself?
Yes, if you have armorer experience and the proper tools. Most shooters have a gunsmith perform the installation to ensure proper alignment and zero. The sights require standard dovetail mounting—your slide cannot be MOS-cut.
Do I get both front and rear sights?
Yes, this is a complete set. You receive the front sight with green dot and orange outline, plus the single dot rear sight, ready to install once mounted.
How long do the tritium lamps last?
Tritium is self-luminous and requires no batteries. The lamps will remain visible for many years, though brightness will gradually diminish over a decade or more of service.
