Given a suitable platform like a Ruger, the old Colt is every bit the equal of the .44 mag.I prefer my 44 magnum in a Ruger Redhawk with a action job. I also have a S&W 629 but I still prefer the Ruger after the action job.
I have a old model Ruger 3 screw .45 Blackhawk whose serial number is in the low three digits that is also fun to shoot. I rescued it from a friend who thought that he had a .44 mag and was loading it all the way up to that power.
