Hi-Viz front sight installation tool for Glock pistols. The 3/16" hex driver tip is sized for the factory and aftermarket Glock front sight screw — standard across Glock 17, 19, 22, 23, 26, 27, 34, 35, 43, 43X, 48, and the rest of the platform. The same driver fits the Walther SW99 and P99 front sight screws, so it doubles as a small-shop armorer's tool for both pistol families.

What it's for:

• Installing or removing a Hi-Viz Litewave, fiber-optic, or steel front sight
• Swapping the factory polymer front sight for a steel or night-sight upgrade
• Replacing damaged or loose front sight screws during a sight swap

Install workflow: clear the pistol, remove the slide, support the slide nose-down on a block, and use the hex driver to back the front sight screw out from inside the slide before lifting the front sight off the dovetail. A small dab of blue threadlocker is recommended on reinstall to keep the screw seated through recoil cycles.

Note: this tool is the front sight screw driver only — for rear-sight installs you'll also want a Glock rear sight pusher.
