Ameriglo I-Dot Tritium Night Sight Set for Glock 17/19/19X/26/45 Gen 5 - Green Front Dot with Orange Outline & Single Dot Rear

The AmeriGlo I-Dot Tritium Night Sight Set brings reliable low-light performance to your Glock Gen 5 pistol. Built around a proven dot-over-dot sight picture, these night sights give you fast, intuitive vertical alignment whether you're training at the range or carrying for personal defense. The green tritium front dot with orange outline stands out clearly in daylight, while the single green dot rear sight keeps your focus on target acquisition and follow-up shots.

AmeriGlo's I-Dot design is trusted by shooters who need sights that work in any condition. The case-hardened steel construction withstands the rigors of regular use, and the tritium vials maintain visibility in near-total darkness without batteries or activation. This set fits Glock Gen 5 models including the 17, 19, 19X, 26, and 45—whether you're running a compact EDC, a duty gun, or a range workhorse.

Installation is straightforward for anyone comfortable with basic gunsmithing, and the dimensions are engineered to drop into factory dovetail cuts without modification. If you've been shooting with plain steel sights and wondering why low-light shooting feels like guesswork, tritium night sights close that gap immediately. The orange outline on the front sight aids target centering in bright conditions, while the pure tritium glow takes over when the sun drops—exactly when you need it most.

Frequently Asked Questions

Will these sights fit my Glock Gen 5 with an MOS slide?

No. This I-Dot set is designed for standard Gen 5 slides and will not fit MOS (Modular Optic System) variants. If your slide has a milled optic cut, you'll need a different sight solution.

What's the difference between the front and rear dot in the I-Dot design?

The front sight has a larger green tritium dot surrounded by an orange outline, which aids aiming in daylight. The rear sight features a single tritium dot in a square notch, creating a cleaner sight picture and letting you focus on the front sight for faster target acquisition.

Do these tritium sights need batteries or charging?

No. Tritium is self-luminous and requires no batteries, charging, or activation. The vials will glow in darkness for many years and won't drain power or fail if left unused.

Which Glock Gen 5 models does this set fit?

This sight set is compatible with Glock Gen 5 models 17, 19, 19X, 26, and 45 in both 9mm and .40 S&W calibers. If you own a different Gen 5 model, check compatibility before ordering.
