Like said above, the .41 Magnum was developed for police duty to replace the .357 Magnum with a heavier weapon that didn't have the excessive recoil the .44 Magnum had. From what I understand the .41 Magnum fell victim to the semi-auto changeover. Around the same time the .41 Magnum would have been adopted the move to semi-autos was also beginning. (I think)

Again like said above, limited ammo and bullet selection will hurt any caliber and there is very little to choose from in .41 Magnum...
