Performance, bro. The 9mm is like a handgun. The .40 can bring down big game. The 9mm DOES hit at range, great for varmints or scaring off teenagers but the .40 for what it costs is actually a CARBINE- meaning it can handle light combat use and kill men at a moderate distance reliably. Below .40 you are dealing with stoppage issues and a bad lack of firepower. The 9mm WILL kill you. For like 3 dollars more a box you have a round and a weapon capable of taking deer and big game. When they made this round, the FBI asked "why do we need a pistol capable of bringing down big game?" my answer is therein- it can easily stop a man, just the same features as a 9mm but with the ability to slam it through a Subaru door or bring down a caribou. Think "9mm magnum"Leon... any reason the .40 is better? I'm always concerned about the cost of burning through ammo... and 9mm is cheaper. But... I am always willing to balance performance against cost savings... So any info that could help us differentiate would be appreciated.
