Model 57 all the way - the .41 is the perfect size for the N frame; .44 (.429 actually) is somewhat small for a steady diet of .44 Magnum ammunition.

Get a 57, then go all the way and load for it. You'll be part of a happy cult. You might also be inclined toward that best of all shotgun gauges, the 16, and the 7x57 in rifle calibers, once you step down the road in caliber cults.
