As of late, more people are purchasing or requesting firearms that chamber the 5.7 caliber cartridge at an alarming rate. These cartridges were initially designed with a military/law enforcement application in mind but have gained significant popularity among civilian shooters who desire the following: Very high velocity, extremely low recoil, and exceptionally high magazine capacity.
Gun manufacturers have created an array of products, including 5.7-caliber handguns and new rifle designs based on this cartridge, giving consumers even greater choices than before.

What is the 5.7×28 mm cartridge?

In the late ’80s, the 5.7×28 cartridge was developed as a lightweight, high-velocity alternative to presently available handgun cartridges.
Unlike most handgun rounds, the 5.7×28 round fires at a larger diameter with much greater velocity than most common pistol cartridges. The 5.7 gives shooters an extremely accurate, relatively mild-recoiling, and flat-shooting cartridge.
Characteristics of typical handgunning devices that have a 5.7mm caliber include:
- Bullet weight between 27 and 40 grains.
- High muzzle velocity.
- Reduced felt recoil.
- High magazine capacity.
- Excellent control of the firearm.
The unique aspect of the 5.7 bullet is its difference in performance when compared with 9mm, .40 S&W, or .45 ACP.
Why Are 5.7 Guns So Popular?
