I have to agree that the .41 mag is the .280 of handgun cartridges! It may even be the .264 magnum of handgun cartridges!
The .41 is a great gun, there just isn't much marketing room between the .357 and .44, for the .41 to make it. But it has survived!
As for the .280, I have a 7MM RM and I love it, but if I had it to do over again, I'd have the .280!
