Is 40 caliber better than 9mm?

40 S&W is essentially just a short 10mm round, it features higher breach pressure than both 9mm and . 45 ACP. It’s a heavier round.

Is 40 more accurate than 9mm?

Hence the FBI chose to make the change to the 9mm round, which usually offers a higher round count per magazine, faster and more accurate follow-up shots, less perceived recoil, and very similar physical bullet characteristics to the . 40 S&W. 40 caliber can wound, injure, incapacitate, or kill.
