The 41Mag didn't have an "Elmer Keith" nor a bunch of years with a previous "special" cartridge behind it.

Bullet selection is a big factor in having a caliber "make it". I can get any shape going in about any weight out there for my 44, not so much for the 41.

I too think it was the semi auto craze that helped with its demise. When the gang banger on the other end of the gun fight has more bullets than you and easier to get more into action, I think that is a bad thing. Since my son is an LEO, I am quite thankful that they give him a 40S&W with a bunch of extra rounds to take with him on patrol.

Our gang bangers 'round here usually have an SKS with 30 rounds or so in them with them as they go about their unwholesome tasks.

FWIW
