The Ruger you are referring to is the Blackhawk or Vaquero. Both are single actions and come with separate cylinders for the different rounds. I have owned 2 Blackhawks with the 9mm cylinders over the years and accuracy was great on all ammo types. Absolutely no keyhole effect in mine. Far from it actually. Very accurate in 9mm and 357. But again they are single actions which of course means no moon clips.
Ruger did make a Speed Six in 9mm, but it was 9mm only and had to have moon clips
