Abstract: A universal sight tool for use with pistol slides to remove, install, and adjust the front and/or rear sights which are carried in a dovetail in the slide. The tool is also useful to drill and tap barrels and receivers for sights, beads and scope mounts. The tool includes a frame mounted to a stand, an adjustable sight carriage to engage a sight to be adjusted, a slide leveler/barrel support, a floor plate, fixed and mobile jaws to engage and retain the slide, and bushings on top of the frame to guide drills and taps for drilling and tapping of barrels and receivers.
