Duration: 14:06

This video compares 9mm and .45 ACP for self-defense, using Clear Ballistics gel blocks for testing. While .45 ACP demonstrated superior terminal ballistics, especially with hollow points, 9mm offers higher capacity and faster follow-up shots due to less recoil. The choice depends on prioritizing stopping power per round versus overall capacity and shootability.

Quick Summary

For self-defense, .45 ACP hollow points offer superior terminal ballistics and energy transfer, while 9mm provides higher capacity and faster follow-up shots due to less recoil. The choice depends on prioritizing stopping power per round versus overall capacity and shootability.

Frequently Asked Questions

What are the key differences between 9mm and .45 ACP for self-defense?

9mm offers higher capacity, less recoil for faster follow-up shots, and typically fits in smaller firearms. .45 ACP provides greater terminal ballistics per round, meaning more energy transfer upon impact, especially with hollow-point ammunition.

How did 9mm and .45 ACP perform in ballistic gel tests?

In tests using Clear Ballistics gel, .45 ACP hollow points expanded more significantly and were captured within the block, delivering all energy. 9mm hollow points still over-penetrated, and both ball rounds over-penetrated, with .45 ACP creating a slightly larger wound channel.

Which caliber is faster for follow-up shots, 9mm or .45 ACP?

9mm is significantly faster for follow-up shots. In testing, 9mm allowed for 5 rounds in 1.02 seconds, while .45 ACP took 1.44 seconds due to its higher recoil and muzzle flip.

What is the advantage of using Clear Ballistics gel for testing?

Clear Ballistics polymer blocks are preferred for testing because they provide consistent, repeatable results. This allows for more scientific and objective comparisons of ammunition performance than torso targets with simulated ribs.
