a 9mm puncturing your heart is a lethal wound that will 100% kill you, it still takes like 5 seconds or so to die from it during an adrenaline rush where the soon to be death can flail the knife around or press the trigger of a handgun. small calibers only brain and spinal cord shots are drop dead injuries if adrenaline is in play and those are quite hard to land. now if you blast someone with a rifle or a shotgun they may drop dead because the bullet do not only punctures an organ but the kinetic energy also causes a shock that makes the body recoil and twich but small calibers dont carry that much kinetic energy.
