Good alternative - Evolution Gun Works Vortex Viper/Venom Sight Mount

I wanted to put a Red Dot sight on a pistol that was not set up for Red Dot sights. I did not want to spend the money to have the slide milled for the sight. The sight mount fit nicely into the existing dovetail, and is holding tight. The sight is only slightly higher than on a milled slide, as was a good alternative to the expense of having the slide milled.
