The Winchester white box 9mm round above brought an HK P30L to a screeching halt.
Further, that lip on the bullet's heel, which is what caused the case to look like that, meant the bullet was wedged snugly enough in the chamber that when the firer attempted to clear the malfunction, the bullet stayed in the chamber and only the case was extracted. The powder was dumped into the magazine. This would have been a fight-ending malfunction.
