Someone needs to study up on terminal ballistics Handgun bullets damage what they actually impact. There is not enough velocity to impart ANY hydrostatic shock to surrounding structures.
Rifle rounds can have that effect but impact velocities are sometimes 3-4 TIMES what handguns are capable of.
"Shock" with a handgun is an outdated myth. Structures damaged + blood loss = effect on target. Nothing else
Structure damage, CNS incapacitation, blood out, air in. Those are the 4 factors that will stop a threat with a handgun. You are correct, hydrostatic shock does not occur with handgun rounds. Somewhere around 2200 fps is the threshold to cause disruption with hydrostatic shock effect, and even then not totally reliable.
