Product Overview

Give your Sig a serious red‑dot upgrade without touching a mill or a file. The EGW Trijicon RMR / SRO, Holosun 407c / 507c Mount replaces your factory rear sight with a rock‑solid dovetail plate, letting you run proven optics on duty, competition, or range pistols while keeping your slide completely unmodified. Machined from 7075 aluminium and finished in a matte black hardcoat, it’s built to handle hard use, recoil, and rough weather without losing zero.

This mount is purpose‑built for standard dovetail Sig slides – it will not work with any optics‑ready Sig that uses a removable mounting plate. If your pistol has a traditional dovetail rear sight and falls within the supported P‑series and compatible models, this plate gives you a low, secure footprint for Trijicon RMR/SRO and Holosun 407c/507c pattern optics. Installation is straightforward with the supplied hardware: remove the rear sight, drift in the plate, secure it, and torque the optic screws to spec. The result is a clean, repeatable mounting solution that improves target acquisition speed and practical accuracy, ideal for Australian shooters who want modern optics performance on proven Sig platforms without committing to a permanent slide cut.

Key Features

• Precision 7075 aluminium construction delivers a strong yet lightweight mount that stands up to hard use on duty, competition, or range pistols.
• Matte black hardcoat finish resists wear and corrosion, helping the mount maintain a low-glare, professional appearance over time.
• Dovetail rear-sight interface lets you add a red dot without permanently modifying your slide, so you can revert to factory sights at any time.
• Compatible with popular optics such as Trijicon RMR / SRO and Holosun 407c / 507c, giving you flexibility to run your preferred red dot sight.
• Designed to fit a wide range of Sig Sauer pistols and other models like the FN 509 and Bersa Thunder series, maximising versatility across your handgun collection.
• Progressive-taper dovetail is engineered for easier installation from left to right, reducing the effort needed to seat the mount securely.
• Included mounting hardware and clear torque guidance (15 in/lbs) simplify installation and help ensure a secure, repeatable zero.
• Low-profile plate keeps the optic as close to the bore as possible, supporting faster target acquisition and more natural sight alignment.
• Non‑compatibility with optics‑ready slides prevents incorrect use, ensuring the mount is only installed on suitable dovetail‑rear‑sight pistols for safe, reliable operation.
• Ideal for shooters wanting to modernise classic Sig pistols with a red dot, improving visibility and speed without the cost of slide milling.
