Here's why I would get the .454 Casull.
Because you can ALSO fire .45 Colts from them! Like two caliber pistols in one.
Of course a .44 Mag will also fire .44 specials and .44 Russian, but I like a .45 better.
Some people think I'm paranoid because I have guns. If I have guns, what do I have to be paranoid about?
