Shot placement matters more then caliber IMHO. Any of the common calibers 9, 45, 40 will get the job done (albeit 357 Sig will do it better), if placed properly.
These days, I just prefer 357 Sig more.

It is better then 45,9 or that 40 "s" something thingy.
You get the capacity and the punch.
There we go, stir the pot a bit more.
