Frequently Asked Questions

What tools are needed to remove and install iron sights on a Glock 43X MOS?

You will need a sight pusher (like a Lyman's), a 3/16-inch thinwalled hex driver for the front sight screw, and protective tape to prevent scratching the slide during the process.

How do Glock sight channels differ from other firearms?

Glock firearms feature an hourglass-shaped sight channel, allowing sights to be removed and installed in either direction. This differs from trapezoidal channels found in many other brands, which restrict movement to a single direction.

What is a critical safety step before working on Glock sights?

Before starting, ensure the firearm is completely unloaded, the magazine removed, and the chamber visually and physically confirmed clear. Also, remove any mounted red dot optic to prevent damage.

How can I protect my Glock slide during sight installation?

Apply protective tape to the slide, especially on the top surface. This will prevent scratches from the sight pusher's vertical and horizontal flats during the removal and installation process.
