9mm vs 45 ACP, WE END THE DEBATE. The Human Torso Test.

Published on February 13, 2022
Duration: 24:44

This video scientifically compares 9mm and .45 ACP using human torso analogs to test terminal ballistics. Modern 9mm hollow points demonstrate comparable or superior performance to .45 ACP, often fracturing bone and expanding effectively. The conclusion favors 9mm due to higher capacity and lower recoil, emphasizing training over caliber choice.

Quick Summary

Garand Thumb's human torso test reveals modern 9mm hollow points rival .45 ACP performance, often fracturing bone. While .45 ACP shows power, 9mm's higher capacity and lower recoil make it favorable for follow-up shots. Training is emphasized as more crucial than caliber choice.

Frequently Asked Questions

What was the main purpose of the Garand Thumb video comparing 9mm and .45 ACP?

The video aimed to scientifically settle the 9mm vs .45 ACP debate by conducting a terminal ballistics test using sophisticated human torso analogs, evaluating how different ammunition types perform against simulated bone and tissue.

How did modern hollow point ammunition perform in the 9mm vs .45 ACP test?

Modern 9mm hollow points, like Speer Gold Dot, performed exceptionally well, fracturing simulated bone and expanding effectively. This demonstrated that modern 9mm ammunition can rival or exceed the performance of older .45 ACP designs.

What is the conclusion regarding the effectiveness of 9mm versus .45 ACP?

With modern ammunition, the ballistic difference between 9mm and .45 ACP is marginal. The presenter favors 9mm due to its higher capacity and lower recoil, which allows for more accurate follow-up shots, emphasizing training over caliber choice.

Why are FMJ rounds considered suboptimal for self-defense based on this test?

The test showed FMJ rounds from both 9mm and .45 ACP resulted in complete pass-throughs with minimal tumbling or fragmentation. This lack of controlled expansion and energy transfer makes them less effective for self-defense compared to hollow point ammunition.
