Gun Gripes Episode 66: The Caliber Debate

Published on April 26, 2013
Duration: 12:02

The caliber debate for self-defense is complex, with real-world studies suggesting .40 S&W and .357 Magnum have high one-shot stop rates. However, modern 9mm hollow points are highly effective, and shot placement is ultimately the most critical factor. Bullet construction significantly impacts performance, and personal preference, accuracy, and comfort in shooting are key for choosing a self-defense caliber.

Quick Summary

Shot placement is the most critical factor in self-defense effectiveness, more so than caliber alone. While studies show .40 S&W and .357 Magnum have high one-shot stop rates, modern 9mm hollow points are also highly effective. Choose a caliber you can shoot accurately and comfortably.

Frequently Asked Questions

What caliber is best for self-defense according to real-world studies?

A 17-year study of actual shootings indicated that .40 S&W and .357 Magnum were tied for the highest one-shot stop rate at 96%. This data is derived from real-world encounters, not just ballistic gel tests.

Does 9mm have enough stopping power for self-defense compared to .45 ACP?

Modern 9mm hollow points are highly effective. While .45 ACP has a larger diameter and significant temporary cavitation, shot placement is the most critical factor. A well-placed 9mm round is more effective than a poorly placed .45 ACP.

How does bullet construction affect self-defense effectiveness?

Bullet design significantly impacts performance. For example, .45 ACP ball ammo has a 62% one-shot stop rate, but Federal Hydra-Shok .45 ACP ammunition increases this to 93%, demonstrating how construction changes effectiveness.

What is the most important factor in self-defense shootings?

The speakers emphasize that shot placement is the most critical factor in a self-defense situation. Choosing a caliber you can shoot accurately and comfortably, and mastering shot placement, are key to effectiveness.
