Critical Duty has an "H" embossed in the flex tip. There are other differences, but that one alone makes ID simple.

I wish they would have shot the ammo from a gun that the ammo was meant for. People look at all the different ammo that over penetrates and think wow that ammo sucks. but in rality its just being shot from the wrong kind of gun. same issue on the link someone else posted. the ammos being shot from a compact. Critical Defense is designed for compacts and Critical Duty is designed for full size guns. I'm gonna see if i can find a ballistics test done with compacts and full sizes. If i find anything Ill post it here for others who may carry a full size.RandyM wrote:this article just came out, comparing ammo in 380, 9mm, 40, and 45, has images of each shot thru gel, good article.
