- Heavy-Duty Corrosion-Resistant Build Crafted from aerospace-grade aluminum alloy for rugged durability, paired with an electroplated iron screw that withstands heavy use. Built to resist rust and last through years of range sessions or garage gunsmithing. - SquareSlide Specific Design Designed for square slides (common on 1911 and Glock platforms). Not compatible with angled or notched slides like Springfield XD/XDM or SW Shield models. - Precision Control The actuator tool features fine adjustment threads and a side-view window for precise fine adjustments. The fixed slide sides and bottom platform stabilize the barrel. Spacers on the fixture are designed to protect the barrel from abrasion and scuffing. - Easy to operate This sight pusher tool is simple to operate; align the tool with the rear sight and make quick and accurate fine adjustments by adjusting the proper components for smooth use. Use scenarios - Range day tuning: Install and fine-tune rear sights on a square-slide handgun such as a Glock or 1911, then confirm alignment quickly with precise adjustments. - Home workshop setup: Replace or upgrade rear sights on a square-slide platform and use the tool to stabilize the barrel while checking alignment without marring components. - Garage gunsmithing across multiple firearms: Repeatedly adjust and verify rear sight position on square-slide models, using spacers to protect barrels and maintain consistent results across sessions.
