I don't really think so (Buffalo Ammunition):
.357 Magnum 4 inch S&W L frame Mountain Gun
.41 Magnum 4 inch S&W N frame Mountain Gun
10mm 5 inch 1911-type
It's pretty clear the .357 Magnum has a slight (but not signficant) energy (and sectional density) advantage over 10mm, but for all practical purposes they are ballistic twins. Double Tap loads their 10mm slightly hotter and their .357 Magnum slightly milder, but they are are still in the same range. When you compare the hottest 10mm loads to the hottest .357 Magnum loads, there's not enough difference to make a difference. The major difference is .357 Magnum is normally found in revolvers and 10mm is normally found in autoloaders.
When you compare the .357 Magnum and 10mm to the .41 Magnum, the .41 Magnum has the clear advantage over both of them outstripping the 10mm by almost 60% with heavier bullets.
It's pretty clear when we look at these numbers (and remember the .357 Magnum was not designed as defence cartridge as pocketable two-inch but as a hunting cartridge for a large frame revolver) the .357 Magnum and 10mm belong in one family while the .41 Magnum is in a totally different league.
All that being said, and FTR, if I had to choose between a two-inch Rossi (of all things) in .357 Magnum and a G27 in .40 S&W, I'd pick the G27 in .40 S&W because it is better suited in that role.
