RomeoZero Mounting Standard

The optics listed below feature the SIG Sauer® RomeoZero Mounting Standard. The Grayguns custom slides with the RomeoZero standard footprint will accept these optics without needing an adapter plate.

The RomeoZero standard features two holes for the screws and four sockets in which the notches on the mount or adapter fit. One notch is in each corner.

This hole and pin pattern is the same as the Shield RMS/SMS mounting standard.

Before placing an order for an optic or slide, ensure the optic will fit the slide. Grayguns can not guarantee an optic will fit our slide even if it has the same footprint hole spacing and layout.

Design differences – including the amount of thread engagement – may make the sight incompatible with your pistol.
