This video discusses the trade-offs between 9mm, .40 S&W, and .45 ACP for duty carry firearms. It highlights that .45 ACP offers significant energy due to its heavy, slow projectile but sacrifices capacity. 9mm, conversely, is faster and offers higher capacity but less energy. .40 S&W was presented as a compromise between the two.

Quick Summary

For duty carry, 9mm offers higher capacity and less recoil with good penetration, while .45 ACP provides more energy and stopping power at the cost of capacity. .40 S&W was an attempt to balance these factors.

Frequently Asked Questions

What are the main differences between 9mm and .45 ACP for duty carry?

9mm uses a smaller, faster projectile offering higher magazine capacity and less recoil, ideal for rapid follow-up shots. .45 ACP uses a larger, slower projectile delivering more energy and stopping power, but typically has lower magazine capacity.

Was .40 S&W a good compromise caliber for duty firearms?

.40 S&W was introduced as a compromise, offering a larger round than 9mm and faster than .45 ACP, aiming for a balance of projectile size, velocity, and magazine capacity.

How does projectile size and velocity affect handgun stopping power?

Larger, heavier projectiles moving slower (like .45 ACP) tend to deliver more energy and create wider wound channels. Smaller, faster projectiles (like 9mm) rely on velocity for penetration and energy transfer.

What is the typical magazine capacity difference between 9mm and .45 ACP pistols?

Full-size 9mm pistols commonly hold around 17 rounds, while full-size .45 ACP pistols typically hold fewer, often around 13 rounds, due to the larger cartridge size.
