that zombie ammo is fine to carry, all that stuff is is Hornady Critical Defense with a green tip instead of red...that is the ONLY difference, i've spent probably about 70 hours this year ballistic testing hornady ammo lines....that said...the best performing ammo (ballisticly) is speer gold dot if your pistol will eat it.....it wouldnt let me reply on the thread so i thought i'd let you know here : ) thanks
