I'm not going to get into a caliber discussion, because almost all guns and calibers fit their purpose: to kill in the appropriate situation.
Yet I know that both the 9mm and .40 P239s are excellent firearms, carried by many professionals I know, including good friends. These are some of the best compact firearms on the market. I know someone who carries both, and says that the 9mm is more pleasant to fire, with lower recoil, which can translate into faster, more accurate firing, with the added benefit of an extra bullet in the magazine. Both calibers kill, yet if you want to punch larger holes in your target regardless of relative recoil and accuracy, then the .40 is better.
