I don't think 230gr FMJ 45acp ammo is great self defense ammo. In studies I have heard that they are about just as effective as the 9mm ball ammo which is not considered great ammo. The question I ask is does any Large PD or Federal Agency use 45 ball ammo for self defense? None that I know of but I am sure there are many here that will tell you a .45 anything is the hammer of Thor when it comes to knockdown "which is a myth". If I lived in NJ then I would carry .45 ball ammo but more likely the EFMJ Guard Dog ammo. If it is all I had when someone kicked in my door and I hadn't loaded up HP in my Mags and all I had was the target loads then like Stone Cold Steve Austin and I would give you a *()* yea and blast away with FMJ. I don't want to kill the neighbors cat by bullets going through my apt walls after they pass clean through a person.
