Stockwell hit the nail on the head, if you're not a reloader the 10mm is the better choice for cheaper ammo and also lower recoil with .40. Even tho 10mm & 40 aren't 9mm or .357, it's much more popular than .41 Magnum and it's a good thing that the 10/40 aren't 9/357 because that means you may likely find some of the ammo at normal prices.
One benefit that I think would make the 10mm revolver an even better choice than .41 Magnum is you can ream the chambers in the cylinder deeper for the 10mm Magnum, which is a legit magnum equal to .41 Mag in power, but would still retain the ability to shoot 10mm Auto and .40 S&W. Would be much more powerful than .357, but not quite .44 Mag in power, however IDK how often full power .44 Mag is needed, probably almost never for most people.
