How heavy are those ballistic shields, and how do they respond to being hit by a round when held by someone? I have seen video of them being shot at while hanging on a post stationary. But it seems to me that if the shield stops a round, all of that energy is going to get transfered into the arm of the person holding it.
When you're talking about energy transfer, the round hitting won't exert any more force than it did in recoil on the firer (so all those guys getting blown 10 ft backward in movies from a shotgun blast is BS... unless the firer goes flying too). So if a round is fired from a 10 pound gun and hits a 10 pound shield the force of impact and the force of recoil will be about the same (discounting friction, rotational forces if it hits off center, etc).
I'd bet it absorbs far more force than a bulletproof vest (due to padding, since flexability isn't as necessary as a vest), in which a non-penetrating handgun hit is often described as similar to being hit in the vest with a hammer.
