If you absolutely had to have a Ruger, they make a light 45 Colt single action that would be a good choice.
Ruger double actions chambered in 44 or 45 - Black Hawk and super Blackhawk are bulky/burdensome in my opinion.
You’d be better off with S&W revolvers, I think.
Id pick the 629 with a 4” barrel. If that’s too heavy then the model 69. A model 25 or 29 S&W with 4” barrels are a good choice.
Other options include the 1873 Model “P” clones in 45 Colt.
My brother had a Super Red Hawk - it was a general consensus that that Revolver was never meant to be carried - heavy, bulky, burdensome.


I prefer classic.
