If I had 41 mag stuff (dies, brass ,bullets) I could understand. The 44 guys claim a much higher muzzle energy and more energy at 100 meters. I am not dissing the 41, if all things were equal I would opt for the 41. But they are not. 44 components are much more widely available at a much lower price. The difference in bullet diameters is only 0.019”.
I have both 41 and 44 with dies for both. I don’t have a preference, I like them both.
In practical reality, aren't most defensive uses of a handgun at much closer quarters than 100 meters?
