Glock Sight Comparison: Ameriglo vs Meprolight vs TruGlo TFO

This article compares three popular tritium night sights—Ameriglo, Meprolight, and TruGlo TFO—intended for use on standard Glock pistols.

• All three sight sets utilize Tritium for self-powered night illumination, though Ameriglo and Meprolight include a white ring for daytime visibility.
• The Ameriglo and Meprolight sights maintain the standard Glock sight profile, while the TruGlo TFO sights are considerably longer due to their fiber optic construction.
• While all housings are described as robust, but there are potential structural concerns, specifically reports of loose optics on TFO models and paint abrasion on Ameriglo/Meprolight.
