FWIW, it looks like I am converting to the 40SW. I've been a firm believer in either .45 or .357. I've had a Sig P226/40 for a dozen years but never cared for it, I still have most of the ammo left that I bought with it

Thursday I bought a Springfield EMP (40), that's the reduced size 1911. I love it! I have 300 rounds through it and it's just as comfortable to shoot as my full sized steel 1911.
I have to admit that the ballistics performance chart for the 180 gr .40SW does look good.
FWIW, Springfield has both a 9mm and 40SW EMP. The 40SW is an all steel frame (32 oz.) whereas the 9mm is an alloy frame that is a half dozen ounces lighter. I think they wisely realized that the 40SW belonged on a 30+ ounce gun.
I've been carrying the EMP since it arrived.
