That's pretty much the same results & conclusion I came up with in all my testing with both calibers. I love my Model 57 S&W but I usually end up carring my Glock 20 with the 200XTP bullet with AA-9 because of the round capacity or my Kimber 10mm because of size & still more rounds than my Model 57...

I got to thinking about this a little more, and i would summarize it this way. With the .41, you can use much heavier bullets than the 10mm. With the 10mm, you can go down to 135 grain, but i haven't seen any 250 grain like with the .41mag. And the 10mm casing is just more efficient.
