Duration: 25:16

This comprehensive review by hickok45 compares the 10mm Auto and .45 ACP calibers using identical platforms like the Glock 20/21 and Colt Delta Elite/1911. The 10mm demonstrates significantly more power, especially with hotter loads, making it suitable for hunting and dangerous game, while the .45 ACP offers milder recoil and is a common choice for self-defense. Ammunition cost and availability favor the .45 ACP.

Quick Summary

The 10mm Auto generally offers significantly more power and velocity than the .45 ACP, especially with specialized hunting or defense loads. Standard 10mm loads have more energy than standard .45 ACP loads, and high-performance 10mm rounds are considerably more potent, making them suitable for dangerous game.

Frequently Asked Questions

What is the primary difference in power between 10mm Auto and .45 ACP?

The 10mm Auto generally offers significantly more power and velocity, especially with specialized hunting or defense loads. Standard 10mm loads have more energy than standard .45 ACP loads, and high-performance 10mm rounds are considerably more potent, making them suitable for dangerous game.

How does the recoil of 10mm compare to .45 ACP?

In similar platforms, standard 10mm loads typically produce slightly more felt recoil, often described as a sharper 'snap,' compared to the .45 ACP's 'push.' However, the difference can be mitigated by pistol design, with polymer frames absorbing more recoil than all-metal frames.

Which caliber is better for self-defense: 10mm or .45 ACP?

For general urban self-defense, .45 ACP is often recommended due to its manageable recoil and widespread availability. While 10mm is effective, its higher power might lead to legal scrutiny in some self-defense scenarios. Standard 10mm loads are viable, but hot loads are typically reserved for hunting or specific defense situations.

Is 10mm ammunition more expensive than .45 ACP?

Yes, 10mm Auto ammunition is generally more expensive and less commonly available than .45 ACP. This cost and availability factor makes .45 ACP a more practical choice for high-volume practice and general-purpose use.
