This video delves into the long-standing debate between .45 ACP and 9mm Luger, arguing for the .45 ACP's superior stopping power in specific scenarios like home defense. It contrasts their historical development, shooting dynamics, and terminal ballistics. While acknowledging the 9mm's advantages in capacity, cost, and recoil for concealed carry, the .45 ACP is presented as ideal for suppressed applications and situations demanding maximum impact.

Quick Summary

The .45 ACP is often considered more dangerous for home defense due to its superior stopping power, stemming from a larger diameter and heavier projectile. It also operates at lower pressures and is naturally subsonic, ideal for suppressed use. While 9mm Luger excels in capacity and cost for concealed carry, .45 ACP provides greater immediate incapacitation potential.

Frequently Asked Questions

Is .45 ACP more dangerous than 9mm Luger?

The .45 ACP is argued to be more dangerous in terms of stopping power due to its larger diameter and heavier projectile, making it highly effective even with non-expanding ammunition. While 9mm is effective, it often relies more on expansion. For home defense, .45 ACP is often favored for its raw impact.

What are the advantages of .45 ACP for home defense?

.45 ACP offers superior stopping power and a more manageable recoil impulse (often described as a 'thud') in full-sized handguns. It's also naturally subsonic, making it ideal for suppressed use, and its lower operating pressure reduces firearm wear.

Why is 9mm Luger popular for concealed carry?

9mm Luger is favored for concealed carry due to its smaller cartridge size, allowing for higher magazine capacity in a given firearm size. It also generally has lower recoil, making for faster follow-up shots, and is more affordable per round.

How does the pressure of .45 ACP compare to 9mm?

The .45 ACP operates at significantly lower chamber pressures, around 21,000 PSI, compared to 9mm Luger, which operates at 35,000+ PSI. This lower pressure means less stress on the firearm's components, potentially leading to a longer service life.
