The TruGlo Tritium Pro Low-Set Night Sights (brand part number TG231G1W) are cut specifically for the standard- and compact-frame Glock 17, 17L, 19, 19X, 22, 23, 24, 26, 27, 33, 34, 35, 39, and 45 (except MOS-slide models), finished on a Black Nitride Fortress Frame for wear and corrosion resistance. A white-outlined green tritium front sight pairs with a plain green tritium rear, so the sight picture reads the same in daylight or after dark. The front sight mounts on the post and the rear dovetails in, both cut to the Low profile that matches these standard Glock slide dimensions. Tritium never needs a battery, and the front lamp’s FOCUSLOCK ring locks your eye onto a consistent focal point on every draw.
