I've been bugging Ruger for over a year to make a lightened version of the Red in .45 Colt for those who want a sturdy DA, but don't want to always be shooting nuclear-level loads.
For standard vel loads, the regular Red's way overbuilt & heavy.
This is not entirely what I wanted, but between it & the Kodiak, Ruger's giving us a great durable DA revolver with its easy reloading, in lighter and/or more compact form, for various uses where Buffalo Bore & CorBons are neither needed nor wanted.
There was a lotta room for expansion in the Redhawk pattern, and Ruger's taking advantage of it.
I don't see Ruger trying to turn the Redhawk into a "cowboy" gun in any way whatever with this new convertible.
Chambering something for the .45 Colt in no way makes it into a cowboy gun.
Neither does a set of wood grips.
The stock rubbers are big & bulky, the new roundbutt convertible is a bit more of a carry gun for some shooters in some contexts.
I have a Tyler T-Grip on my Kodiak to increase inside grip girth, it can also be used on the convertible, if you need more to hang onto.
This, and the Kodiak, gives us more options in the Redhawk, and I'm glad to see Ruger doing both.
If neither creates any interest for you, go with one of the other versions.
