GS Retrofit Optic Screws

Shorter Replacement Screws for Mounting Optics

When installing an optic on a slide that has been milled it is often necessary to use a shorter screw than what comes from the optic manufacturer. This is especially true when mounting
the optic directly to the slide without any adapter plates.

The screw is an M4 x .7 x 9mm Torx Flat Head Screw

Sold in a set of two, this screw works with all generation slides for the following Glock models:

507K on G43X, G48 retrofit
EPS on G43X, G48 retrofit
RMSC on G43X, G48 retrofit

507K, 407K on G17/19 and similar

507K, 407K on G20/21 and similar

This screw will also work with other manufactures slides as long as you are using the optics mentioned.
