Thread "size does matter" by Hugh Johnson, perhaps you meant to type your name as Huge Johnson?
While larger caliber is a good thing, "it's not the size that matters it's how you use it." So, missing the target with a 45acp is worse than hitting with a 9mm or even a 380auto. That said, I typically CC a 9mm, but OC a 45. If you can't handle the stick then it's worthless.
