A Glock 19 shot to the temple has a very high probability of causing immediate death, the kinetic energy and proximity to the brain causing devastating damage. However, death is not always instantaneous: if the brainstem is not directly hit, the bullet can still cause severe intracranial hemorrhages or brain edema, leading to a deep coma and death in the following hours or days. Even if vital areas such as the brainstem are not affected, the resulting brain hemorrhage is often fatal in the short term. There are extremely rare and negligible chances of survival.
