Truglo’s TFX Pro sights (part no. TRUTG13GL3PC) are built for Glock Slimline 42, 43, 43X, and 48 pistols. TFX Pro takes the same chemical-resistant, tritium/fiber-optic TFX construction and adds a contrasting colored front sight and a U-notch rear, pairing an orange front sight with a green rear for a fast, high-contrast sight picture, so the eye finds the front sight first for a faster sight picture.

The rear sight also carries an aggressively angled front edge, which lets you rack the slide one-handed against a belt or holster edge in an emergency. It is built for shooters who want the best reliability, visibility, and accuracy from a day/night sight.
