Why 5.7 Can Never Compete With 9mm For Self Defense

Published on May 5, 2023
Duration: 18:16

The 5.7x28mm round, while offering low recoil and high capacity, faces significant hurdles in self-defense compared to the established 9mm. High ammunition costs and limited availability of effective 5.7mm defensive loads are major drawbacks. The 9mm benefits from over a century of R&D, a vast ecosystem of firearms, and readily available, effective hollow-point ammunition, making it the dominant choice for self-defense despite the 5.7's technical advantages like its Tempo barrel system.

Quick Summary

The 9mm cartridge remains dominant for self-defense over 5.7x28mm primarily due to its extensive R&D, leading to effective hollow-point ammunition and a wide ecosystem of affordable firearms. While 5.7 offers low recoil and high capacity, its ammunition cost and availability are significant drawbacks for widespread defensive use.

Frequently Asked Questions

Why is 9mm generally preferred over 5.7x28mm for self-defense in the US?

9mm is preferred due to its extensive R&D history, leading to effective hollow-point ammunition and a vast selection of affordable firearms. 5.7x28mm ammunition is significantly more expensive and less available, limiting its widespread adoption for defensive use despite its low recoil.

What are the main advantages of the 5.7x28mm round?

The 5.7x28mm round offers extremely low recoil, a flat shooting trajectory, and allows for high magazine capacity. It's also noted for its minimal bullet drop at longer ranges, making it an excellent training round and suitable for specific applications.

What is the Smith & Wesson Tempo Barrel System?

The Tempo Barrel System is a gas-operated mechanism used in the S&W M&P 5.7. It keeps the barrel locked until the bullet passes a gas port, which helps ensure reliable extraction and contributes to the pistol's flat shooting characteristics.

How does the M&P 5.7 compare in weight and capacity to the 9mm Equalizer?

The M&P 5.7 weighs 1 lb 10.3 oz unloaded and holds 22+1 rounds. The 9mm Equalizer weighs 1 lb 8.0 oz unloaded and has a capacity of 13+1 rounds. The 5.7 offers higher capacity but is slightly heavier.
