It started life as a 5.5 inch .44 mag Redhawk. It made a trip to Mag-Na-Port International perhaps a dozen years ago. It had the barrel cut to 4.5 inches, crown inverted, forcing cone recut, chambers polished and numbered, action tuned, new wollf springs, CMore sights, and was ported. I think that was all. I have never shot a finer revolver, including some of those vaunted Smiths with their glass tuned actions. I prefer a smooth stocked magnum revolver to rubber grips or checkered wood, which is why it wears ivory.
I have had many offers to buy it from people who have shot it and said it is the finest .44 magnum they have shot. Ok, that sounds a bit prideful, but I simply love this revolver an no one who has shot it has ever said anything but the same thing. I have taken a whitetail every year with it for at least 15 years. As far as the porting goes, when I first got the revolver if I shot 50 full bore magnums the hand would start getting tired and eventually my grip would weaken and split the webbing between my thumb and forefinger. After no such problem at all. My brother in law has had his Redhawk done in a similar manner after shooting mine.
I highly recommend Mag-Na-Port Int. They are a great group to work with, and it is a great place to vist should you get the opportunity.
