Are you sure the Blackhawk wasn't a 44 special? And the Super Blackhawk is 44 magnum. ( and is a heavier built revlover )
I don't think the non-super Blackhawk is built in 44 mag.
BOTH of these are single actions, the Redhawk or Super Redhawk are double action revolvers.
You could confirm that very quickly with Ruger website or Ruger Forum has plenty of Ruger experts.
