Edwin Sarkissian, an established firearms content creator, conducts a practical penetration test comparing 9mm and .45 ACP ammunition. The experiment utilizes 24-gauge sheet metal discs to evaluate the stopping power and penetration capabilities of each caliber. The results highlight the distinct characteristics of each round: 9mm offers superior penetration, while .45 ACP delivers greater impact force and deformation.

Quick Summary

In a ballistic test comparing 9mm and .45 ACP, 115-grain 9mm FMJ penetrated 13 discs of 24-gauge sheet metal, while 230-grain .45 ACP FMJ penetrated 11 discs. The 9mm showed superior penetration, whereas the .45 ACP caused more significant deformation and larger impact holes, highlighting differences in velocity versus momentum.

Frequently Asked Questions

What was the primary objective of the 9mm vs .45 ACP test?

The test aimed to compare the penetration capabilities and impact force of 9mm and .45 ACP Full Metal Jacket (FMJ) ammunition by firing them through multiple layers of 24-gauge sheet metal.

How did the 9mm ammunition perform in the penetration test?

The 115-grain 9mm FMJ ammunition successfully penetrated 13 discs of 24-gauge sheet metal and created a significant dimple on the 14th disc, demonstrating superior penetration.

What were the results for the .45 ACP ammunition in the test?

The 230-grain .45 ACP FMJ ammunition penetrated 11 discs of 24-gauge sheet metal and stopped at the 12th disc, showing less penetration but causing more violent deformation.

What is the key takeaway from the 9mm vs .45 ACP comparison?

The 9mm offers better penetration due to higher velocity and a smaller profile, while the .45 ACP delivers more stopping power and destructive force, creating larger wound channels or impact points.
