probability as possible of penetrating deeply enough to disrupt a vital organ.
apart from the permanent cavity”, Fragmentation does not reliably occur in soft tissue handgun
wounds due to the low velocities of handgun bullets. When fragmentation does occur, fragments
are usually found within one centimeter (.39") of the permanent cavity.4 Due to the fact that most
modern premium law enforcement ammunition now commonly uses bonded projectiles (copper
jacket bonded to lead core), the likelihood of fragmentation is very low. For these reasons,
wounding effects secondary to any handgun caliber bullet fragmentation are considered
gunshot wounds, that this equates to a range of penetration of 12-18 inches, depending on the size

properly designed, expanding handgun bullets, this objective is realized, albeit more consistently
with some law enforcement projectiles than others.
