I guarantee you that's part of the lawsuit. The principle is the same regardless of the caliber, so why give the gun-banners the opportunity to shove the case off into the weeds of "cop killer" bullets and "automatic" semi-automatic pistols? Did you know that New Jersey, for example, prohibits hollow-point ammo, and simple possession is a crime?
In Chicago, I would add one number to that and go with the .223 handgun.
