Sig Sauer Electro-Optics Romeo1 Mounting Kit - Black Steel - Fits Glock Non-MOS

The Sig Sauer Electro-Optics Romeo1 Mounting Kit is a factory replacement handgun mounting kit purpose-built for the ROMEO1 reflex sight. This non-MOS variant is configured to install the Romeo1 onto standard Glock pistol slides that were not cut at the factory for an optic, allowing shooters to add a red-dot to their pistol using Sig Sauer's own OEM hardware.

Each kit consists of a dovetail block and a matching spacer. The dovetail block replaces the pistol's factory rear sight and clamps directly into the rear dovetail cut on the slide, providing a rugged, low-profile mounting platform that co-witnesses with the Glock's existing iron sights. The kit is machined from steel with a black finish for long-term durability and corrosion resistance.

This specific SOR1MK001 kit is intended for standard 9mm/.40 S&W Glock models with a 25.5mm slide width. It is not compatible with .45 ACP Glock pistols (which use a 35mm slide width) and is not the correct kit for factory MOS slides, which require Sig Sauer's MOS adapter plate system instead. Always confirm slide width and model before installation to ensure proper fit.

Use this mounting kit to replace a lost or damaged OEM Romeo1 mount, or to move an existing Romeo1 sight from one non-MOS Glock to another. The dovetail mount installs with standard gunsmithing tools and integrates the Romeo1 sight securely to the slide without requiring permanent modification.
