The EGW Vortex Viper/Venom sight mount (EGW part no. 49290) is a direct dovetail replacement that lets you run a Vortex Viper/Venom reflex sight on your Ruger SR9/SR40. It installs in place of the factory rear sight, so the red dot sits at the correct height and position for a proper co-witness with your stock irons where the platform allows it. Whether you carry this pistol for concealed carry, home defense, or duty use, a slide-mounted reflex sight speeds up your first shot and keeps both eyes open for target acquisition. EGW builds these mounts specifically for this pistol’s dovetail geometry rather than a one-size-fits-all plate, so fitment stays tight and repeatable.

Key Specifications

• Machined to accept the Vortex Viper/Venom reflex sight footprint, so the optic seats directly on the mount without a separate adapter plate.
• Direct fit for the Ruger SR9/SR40, replacing the factory rear sight dovetail on this specific platform.
• Falls in EGW’s Tactical mount category, matching the low-profile design used across this product line.
• Finished in black, matching the factory finish on most service and carry pistols.
• Installs as a dovetail-based replacement for the factory sight, keeping the swap straightforward for a gunsmith or experienced owner.
