Dr. Andreas Grabinsky (Anesthesiologist) from Seattle, talks about GSW's. He works with the surgeons and trauma team in the OR. He provides a interesting look at ballistics from their perspective. Essentially he considers a handgun wound, a handgun wound, and that common calibers lack power. He also makes distinctions between the types of damage seen from the traditional rifle round and the modern small caliber high velocity rounds.

No, this is not a direct 9mm vs .45 comparison. However it does illustrate how silly the 9, .40, .45 debate is. The Dr. clearly shows the general lack of "power" of the common handgun round. Popular modern service calibers have nearly identical performance and are all built to (and do) perform within the same IWBA and FBI specs. Yes, on paper some rounds do have a ballistic edge over others, often at the expense of capacity, recoil and follow up speed. You can see the insignificance of arguing over 15, 20 or 50ft Lbs energy difference in cartridges making 400- 450ft lbs of energy when a .308 makes nearly 3,000ft lbs. That pretty much puts the insignificance of a 30ft lb difference into perspective.

I did not create, nor do I own the content of the Dr's presentation. This video is not monetized.
