The Ameriglo I-Dot Tritium Night Sight Set fits the Glock 17, Glock 19 and Glock 22 and replaces the factory front and rear sights. The I-Dot layout puts the emphasis on the front sight. In low light you see one bright front dot over a single rear dot, so your eye goes straight to the front sight instead of sorting out a three-dot picture.

The front sight carries a green tritium lamp with a white outline for daylight visibility, and it measures .180" wide. The rear sight carries one green tritium lamp with no outline, so it gives you a reference in the dark without competing with the front. The rear notch is .180" wide.

Features:

• Front: green tritium lamp with white outline, .180" wide
• Rear: single green tritium lamp, no outline, .180" wide notch
• I-Dot layout for fast front-sight acquisition with rear illumination retained
• Sold as a front and rear set
• Fits: Glock 17, 19 and 22

Install and verify: a sight pusher is the cleanest way to swap the rear sight. Center the rear in the dovetail, secure the front sight, then confirm zero at the range. Your point of impact can shift compared with factory sights.
