I only have one 40 S&W handgun remaining in my collection. I prefer the 9mm for affordablity and capacity. There is no difference in accuracy, although most shooters will say that they can shoot faster follow up shots with a 9mm.
I will say that during the post election run on ammo. The only stuff I could find with any regularity was 40 S&W ammo. That's why I keep at least one firearm in my stable chambered in the 40.
