The .41 Magnum is a typical "middle child" though and will never have the popularity of the .357 or .44. Some folks have been saying it's lack of popularity will cause it to disappear...then again, they have been saying that for decades.
I have had mine since 1993, when it was only being produced by S&W and Ruger, as I recall. Today, a look through a Shooter's Bible will yield more manufacturers and models being produced in 41 Mag..
