To kgpcr who said last night that after I fell asleep; "here we go again. another group trying to tell you a 9mm is as good as a .45." That is in my opinion very short sighted and totally NOT what this discussion is all about. I can only assume you have not read all of the Aqeous posts or perhaps did not gather my intent. As of right now its seems like there are substantial ballistics similarities between 9mm, .347, .an 40 S&W (JHP) and then at the higher spectrum of expansion (something like 0.2") there are equal similarities between the 10mm and .45ACP (JHP) I don't think any one here has said flat out the 9mm is better that the .45 ACP.
