I don't know of a handgun scope that has an erector housing thats beefy enough for constant dial-up shooting, I know they have the cds system but it's more of a gimmick than a reliable elevation set-up.such as a nightforce s&b or even a leupold mk5.just sight it in and hold over for long ranges.I know that's not what you're looking for but such a thing doesn't exist right now.
