Ameriglo sight installation tools for the professional. One of our most popular gunsmithing, armorer and do it yourselfer products are the family of sight adjustment tools for Glock semi-automatic pistols. With tritium style night sights common on most guns and sold today there is a need for a more precise method of installation and adjustment. The traditional method of installing and adjusting sights with hammers and punches will damage or destroy the sights and void any warranties. This method can cause the tritium vials to be destroyed or leak. Ameriglo designed these tools to safely install these sights and all other non tritium sights without damage and with precise placement. This model is for sights that have a taller profile than standard sights. (such as Ghost Rings etc.)
