Hi everyone. I was just wondering what your thoughts are on the 40s&w vs the 9mm. Which one you prefer to carry and why. I carry a 40 because I like the extra knock down power vs the 9mm and just like the way that a 40 feels when fired. I love the 9mm and have a T series Browning Hi Power and have always loved it, but I think that with the extra knock down power with only having to give up a couple rounds if any make the 40 a better choice for me.
