I fra Mejico , what i mean is more damage done by the larger round ,if that makes any sense . Stopping power, Knock down power ,"You say tomato, I say tomahto"
i Agree the 9mm is so accurate and very easy to control your patterns compared to a .40 or .45. Sure the .45 &.40 have more knock down power but the 9mm will get the target with much greater accuracy.
