Duration: 13:03

This video provides a direct comparison between 9mm +P and 10mm Auto through various barrier tests, including lumber, sand, concrete, and steel. While 10mm consistently demonstrated superior penetration and energy, especially through steel, 9mm +P performed better than expected in some tests. Chronograph data confirmed 10mm's higher muzzle energy, but the comparison highlights the nuanced performance differences between these popular handgun calibers.

Quick Summary

In barrier testing, 10mm consistently outperformed 9mm +P. While 10mm penetrated lumber, plywood, and 1/8-inch steel, 9mm +P failed in these tests. Both calibers struggled with sand and concrete barriers, but 10mm showed significantly more energy (616 ft/lbs vs 456 ft/lbs).

Frequently Asked Questions

How did 9mm +P and 10mm perform in a lumber and plywood barrier test?

In the test, the 9mm +P (115 gr FMJ) failed to fully penetrate the plywood backing, while the 10mm (180 gr FMJ) successfully punched through both the lumber and the plywood.

Which caliber, 9mm +P or 10mm, penetrated 1/8-inch mild steel more effectively?

The 10mm caliber successfully penetrated the 1/8-inch mild steel barrier. In contrast, the 9mm +P caliber only managed to create a significant dent in the same steel plate.

What were the average velocities and energies for the tested 9mm +P and 10mm loads?

The 9mm +P load averaged 1336 fps with 456 ft/lbs of muzzle energy. The 10mm load averaged 1242 fps with a higher muzzle energy of 616 ft/lbs.

Did either 9mm +P or 10mm penetrate 6 inches of sand in the test?

No, neither the 9mm +P nor the 10mm caliber were able to penetrate the 6-inch sand block to reach the target behind it, resulting in a draw for that specific test.
