Egw Sight Mount For Vortex Viper/Venom Fits Ruger Sr9/Sr40 Black

The EGW Sight Mount for Vortex Viper/Venom on Ruger SR9/SR40 is a direct-replacement dovetail mount that lets you run a modern red dot sight on a classic SR-frame pistol. If you're looking to upgrade your SR9 or SR40 with the speed and accuracy of a red dot—whether for competitive shooting, duty work, or personal defense—this mount bridges the gap between your gun's factory dovetail and optics like the Vortex Viper or Venom. It installs where your rear sight was, so you can swap it off and restore iron sights whenever you need to.

EGW engineered this mount with a progressive-taper dovetail for smooth, hassle-free installation. The design is straightforward: remove your rear sight, slide the mount into the dovetail, and you're ready to bolt down your red dot. The mount comes with the fasteners you need—button head cap screws for Vortex sights, plus flat head options for Burris FastFire and Docter optics—and a 5/64" allen wrench fits all of them. Blue Loctite and a 15 in/lbs torque spec keep everything locked in place without over-tightening.

This is a straightforward accessory that works best installed by a gunsmith, especially if you're not familiar with dovetail mounting. Keep in mind it won't fit the SR9E or SR22 variants, and as with any firearm modification, check your gun's warranty before proceeding. Once mounted, you'll have a rock-solid platform for your optic and the flexibility to run irons again if your needs change.
