After shooting my C in 357, 40, and 9 I can say I favor the 9mm. After looking at some ballistic tests on modern hollow points, I really like the critical duty but thats me, I will stick with the 9.

I also own a fs 40/9 and both size 45s. I really like the 9. After I finish some work on my house I will be going with a core 9.
