Hegshot87 provides an analytical comparison between the Smith & Wesson M&P 5.7 and 9mm handguns for self-defense. He highlights the 5.7's advantages in low recoil, high capacity, and flat trajectory, while acknowledging the 9mm's dominance due to lower ammunition costs, wider availability, and a more established ecosystem of firearms and ammunition. The M&P 5.7's unique Tempo Gas-Operated barrel system is detailed, showcasing its potential for reduced felt recoil and improved shooting dynamics.

Quick Summary

The 9mm cartridge remains dominant for self-defense due to its extensive R&D, lower ammunition costs, and wide availability of firearms and effective defensive loads. While the 5.7x28mm, as seen in the Smith & Wesson M&P 5.7, offers advantages like reduced recoil and higher capacity, its higher ammunition price and limited market ecosystem prevent it from overtaking 9mm for general self-defense use.

Frequently Asked Questions

Why is 9mm still dominant over 5.7x28mm for self-defense?

9mm dominates self-defense due to over 120 years of R&D, leading to cheaper, widely available ammunition and a vast ecosystem of effective defensive firearms. While 5.7x28mm offers lower recoil and higher capacity, its ammunition cost and limited firearm options hinder widespread adoption.

What are the key advantages of the Smith & Wesson M&P 5.7?

The M&P 5.7 excels with extremely low recoil, a flat shooting trajectory, and a high magazine capacity of 22+1 rounds. Its unique Tempo Gas-Operated barrel system contributes to its shootability, making it an excellent training tool and potentially faster for follow-up shots.

What are the main drawbacks of the 5.7x28mm round for self-defense?

The primary drawbacks of the 5.7x28mm round are its significantly higher ammunition cost and limited availability compared to 9mm. This economic factor, combined with fewer firearm options, makes it less practical for widespread self-defense use.

How does the M&P 5.7's Tempo Barrel System work?

The Tempo Gas-Operated barrel system in the M&P 5.7 keeps the barrel locked until the bullet passes a gas port. This system utilizes gas pressure to aid in reliable extraction and contributes to the firearm's exceptionally flat shooting characteristics and reduced felt recoil.
