Just a comment/thought about barrier penetration: We have to train for it. I carry 220gr (45ACP) Hornady Critical Defense because I want the barrier penetration capability before the HP expands. The reason is my geographical location: people wear leather and thick jackets half the year...but I train to vector shots to avoid hitting with over penetration if it becomes a concern. Example, dropping to one or both knees to cause rounds to angle upward, shooting downward towards groin (pelvic girdle hit puts anyone down immediately), etc.
If one doesn't train for this, or just train shooting paper from a typical stance with a 2-handed grip, then I'd recommend avoiding ammo designed for penetration and stick to typical JHP's for SD use, like HydraShok, Corbon, PDX, American Gunner, Golden Saber, etc....
Naturally if carrying FMJ ammo, over penetration is much more probable....
I personally don't care for frangible ammo for SD use, but would rather someone carry that than FMJ, or God forbid not carry at all!
While over penetration is always a concern , I recently read the occurrences of it happening and hitting an innocent is fairly unusual....
L8R's!

As for over-penetration, rule #4 still applies: Identify your target, and what is behind it. Never shoot at anything that you have not positively identified.
Remember, there is no guarantee that a JHP bullet expands. It may just zip though its intended target. Also, you might just miss your intended target. Now what? What's your intended backstop? In many dynamic situations, there is no good answer for that. When your life is in danger, you need to act fast and decisively. That's one reason why shooting downward towards the groin is sometimes recommended no matter what ammo you shoot. However, shooting someone in the chest is more likely to stop the threat than shooting someone in the pelvic area. Also, when in close contact and shooting unsighted from the hip, shooting at the pelvic area is a level shot and not downwards. In this case, shooting upwards is recommended.
As for vectoring shots by taking a knee, that's for specific situations only, like shooting from behind cover. Taking a taking a knee means you are not moving. Not moving means you are a stationary target that is easy to hit, just like at the range.
EDIT: That's 220gr Critical DUTY.
Also wanted to point out it's a polymer tip HP, giving better initial penetration before the HP expands.
See manufacturer info for details...
I know both rounds pretty well and suspected that this was a typo. Critical Defense is not barrier blind. Critical Duty is and is a law enforcement round. In any case, expansion is not guaranteed, neither is a straight line of travel through a body.
Ahuh
I'm assuming that means he's agreeing??
