the truth be told....there is no reason other than you CAN! If you were to get only one(1) gun, then, for sure, get the .44 Mag. In fact, I load the magnum brass with medium loads that are equal to or lighter than the .44 Spl. and they are very, VERY, accurate. I have found that the .44 Magnum is extraordinary with regard to accuracy...certainly bullseye accuracy...BUT, does not have the kind of fast shot recovery as a Bullseye .45. In slow fire, my tuned .44's will shoot as well as my 945. That considered, you still have the option to go hunting for most medium North American game, have a perfect cartridge for self protection (it is a stopper) and one that will not beat you to death. The full house loads can intimidate an inexperienced shooter, but lots of practice can eliminate that. Like anything else....I drive a Corvette Z06 as my everyday driver and it is a pleasure. When someone else is given the wheel, it is frightening. Personally, I live(and love) fast cars and big bullets.
I carried this for years......
but modern science and technology have lightened the load......
however, for a carry gun, magnums not needed.
I would still buy the MAGNUM for one gun.....
