The AmeriGlo 3XL night sight set for Glock is an optic compatible iron sight set built tall enough to clear a slide-mounted red dot (AmeriGlo part no. GL-193). Both ends carry tritium, a green front lamp and a rear sight with a single green tritium dot, so the sight picture still glows when the light fades. The 3XL height gives an elevated co-witness sight picture and doubles as back-up irons if the optic ever fails. AmeriGlo lists the set for all Glock models, including MOS slides. It suits a carry or duty pistol that wears a red dot and still needs irons worth trusting behind it.

Key Specifications

• The sights are night sights with green tritium in the front blade and in the rear, which keeps a visible aiming point in low light.
• The size is 3XL, the tall configuration that lifts the irons above a slide-mounted red dot for co-witness.
• The front blade is 0.365-inch tall and 0.125-inch wide, a slim post matched to the tall rear.
• The rear sight is a single green tritium dot (i-Dot) with an overall height of 0.451-inch, which keeps the dot easy to find over the front post.
• The rear notch is square and 0.15-inch wide, giving a clean, simple lineup with the front blade.
• Fit is all Glock models, including MOS slides, so one set covers the whole Glock line.
• The set includes a front sight and a rear sight, both with a case hardened finish for wear resistance.
