There is no meaningful difference in the 9mm Luger and the 40S&W other than the 40 punches slightly larger holes in paper.

They just closed this same question / post on another forum because it went on and on with nothing decided except that you ought to shoot the one you shot best.

This article might help you decide. In defense of the 9 http://www.handgunsmag.com/ammunitio...803/index.html

funny thing about personal preferences... everybody has 'em! LOL!
I too like the 9mm. I can put a lot of rounds down range and hit what I am aiming at (for the most part!). I've shot them both and just prefer the comfort of the 9.

I don't think I completely agree with you rx7 (love that car!), even though I still prefer the 9, I realize that what the 9 lacks in energy, I need to make up with accuracy and quantity.

Here is a neat calculator that generates a number to represent "efficacy". All you ballistics nerds (you know who you are!) can play with this and see in black and white some data. Its not a goat test or gelatin block, but it's certainly interesting!

for the house, I'll still rely on my shotgun, but out and about, it'll be the 9mm for me! (after my ccp comes in next month!)
