There are still a lot of trainers that preach the "any caliber that starts with 4". My training in Cali listed "stops" what ever that is starting with 9 then 40 then 45 being best. Don't know but I can give my wife any of my 9's and she shoots them just fine. 40 is too snappy for both her and my 31 YO son.

yes the recoil on a 9mm is nicer then on a 44 magnum, using full power ammunition.
Yes, you may be able to put more rounds into the head of a bear chewing on your leg with a 9mm.
But you only need ONE 44 magnum slug to hit the bear in the head to make it stop chewing on your leg.
I thought that the original intent for the 40 was to have a "4" caliber that would be greater than the 7-8 round mag (e.g., 45 ACP in a 1911) -- that was "double stackable" (14+).
