"P.S. One question for the folks who shoot .45's and now 9x19's in revolvers. What's the attraction?..."[B!ngoFuelUSN]
Hey Bingo,
Two big attractions, first off, both calibers use moon-clips which are a Godsend. They make for very fast reloading in a gunfight, and you can't put them in backwards (when reloading) even if you are blindfolded, whereas with an autoloader you can (under stress) try to put a mag in backwards thus wasting precious time.
Secondly, you don't have to hunt down your empties, all bent over, picking up all that spent brass... when shooting a 1911 I always lose some in the grass, whereas the brass stays put in a revolver. ( I handload.)
As for the 44Mag, once the shooter has learned to ride the recoil, they are a joy to shoot.
