I'm looking to get a Ruger Redhawk in 45 colt.
That is sweet! I love the Ruger revolvers, they are built like tanks. One of my .357 Magnums is a Ruger SP101 which I just love.
I intend to add the following Rugers to my collection
GP-100 KGP-161 SS .357 Magnum
Super Redhawk KRSH9440 .44 Magnum
Super Redhawk KRSH7480 .480 Ruger
Super Redhawk KRSH7454 .454 Casull
Ruger doesnt make them in that configuration currently, but there are lots of them out there on the used gun market. Funny thing is, the redhawk is so strong, you can shoot 45 colt handloads in it that would seriously kill a Colt single action army.
