The mp5 is a 9mm. A .223 doesn't over penetrate as much as you might think it would.
The FBI has conducted studies that prove that .223 is superior to pistol caliber carbines (including 10mm MP5's) in most aspects, including potential injury to innocent bystanders.Either way...
I didn't know agencies were switching calibers/weapon systems to .223 calibered systems.
It probably was inspired, at least in part, by the North Hollywood shootout, where police were outgunned and the BGs had body armor.The main reason as I understand it is that more and more the bad guys are using body armor and the 9mm just can't defeat it.
Agreed....If you are carrying a rifle, carry a RIFLE.
You should be thinking that the ad agency probably doesn't know what a swat team does anyway.Well it seems that every ad I see showing a SWAT team everyone now has an AR based weapon. Are you saying their ARs are chambered in 9mm?
The fragmenting of the steel penetrator SS109 is not unique, it's not even just a .223 thing... 55gr M193 yaws and fragments as well, along with many other .223 offerings and in other calibers as well.The steel penetrator in the milspec ammo is designed to upset the bullet upon penetration and cause it to "yaw". When it does so, the bullets breaks apart.
I think there is a big benefit to a .223 over a 9mm in a tactical siuation. Like aiformula said, permanent wound channels do not happen with low velocity pistol ammo.
