well, I might agree with you Lazs if I had experience with as many different calibers and loads as you have... maybe its a case of ignorance is bliss.
I can't judge which caliber out of all of them is the best ballistically for my purposes (social work), and i'm probably confusing the issue by associating caliber with a specific gun, but so far, I've enjoyed using this caliber - in this handgun - more than any 9mm semi auto, more than any 38s, or 45s.
I do like the 357 mag in revolver for social work and .44 in revolver for goofing around... but I need the semi auto, and I LOVE the P226. Whats so bad about the .40 ballistically for my purposes?
