.40 the 9mm is a joke. why do you think so many LEO's and the FBI got away from it.
The FBI got away form the 9mm, because they made a total mess of an operation in miami and made themselves look like armatures. They had to blame something rather than themselves.
The 9mm is the most used handgun ammo fact. It was used by the Germans and other armies in ww2 . Are you seriously saying that the Germans used a ineffective round during ww2 , it is used by most police forces world wide.
So it make it hard to take seriously someone that says it is a joke. They have a right to their view but obviously dont know what they are talking about.
