I had both. Back in the Bush 1 days with gun restrictions starting to get more stupid,yup said more stupid, could say stupider.
I had to make a choice. I like both, but factory ammo and components for the 41 mag are not nearly as common as 44 fodder, at the time there were only 2 factory loads for the 41. I picked 44 and have not looked back. If I could have only one gun it would be a 44 magnum.
