Video: Jiggle, jiggle, jiggle. That's what it looks like from afar when a fully automatic glock starts shooting its bullets at the ballistic gel dummy. And it's almost funny how the gel moves! But then you look a little closer and see the true damage of the gun and it's a whole lot scarier. The bullets spread open upon impact with the gel for maximum damage and then basically torpedoes itself into such spiraling damage that it's so very frightening.
