The shots mostly just penetrated the first two or three layers, but JJ's torso area was the most heavily armored out of all of his suit. He had the suit designed to slightly detach from the parts of his stomach most required for moving, as well as guard them. So, he didn't have to sacrifice movement for protection. Anyway, JJ's sword completely missed, but he tried to save its momentum by spinning into a pirouette, and the sword came back around a second time. This time, it was aimed for JT's head. [spoiler] A coilgun revolver, are you kidding me? That has to be significantly weaker than a full-on gauss cannon.[/spoiler]
