You get what you pay for with ammo. .40 is going to more expensive than 9mm simply because it's not as readily available as 9mm.

Nobody who has been shot has ever been thankful it was 9mm. You can compensate for the bullet size with velocity and type of round.

A fast 9mm hollow point round will do every bit of damage a .40 with average velocity.

The gun will normally have great ammo that should not have to be used and replaced.
from the distances I'm working with, I should be essentially 100% CBM on my first shot for sure. So i suppose comfort level will trump in the event of multiple targets. Glock 19 it is, most likely.
