I have a P226 I want to mount a Venom on. Need suggestions for a decent slide mount. Have seen ADE Advanced Optics and Docter. Suggestions please. Thanks

I'm confused by the question. Are you looking for a mount that might use the existing dovetail? In which case the word decent doesn't apply, they all suck. Or are you looking for someone who can mill for a Vortex?

For use in the existing dovetail. Thanks

EGW makes a mount for your purpose.

and all the dovetail choices are poor, at least if you are doing more than experimenting. If you can't have workable backup irons the setup is problematic. FWIW
