A case for the 5.7

The 5.7 cartridge is a relatively new round in the world of pistols, but it has quickly gained a reputation for its ballistic advantages and practical use. In this blog post, we’ll explore what makes the 5.7 cartridge unique and how it compares to more traditional pistol cartridges.

First, let’s talk about what the 5.7 cartridge is. It was developed in the late 1980s by FN Herstal, a Belgian firearms manufacturer, and was originally designed for use in their P90 submachine gun. The round is also used in the Five-seveN pistol, also made by FN Herstal. The 5.7 cartridge is a small, bottlenecked round that fires a 5.7mm bullet at high velocities.

One of the main advantages of the 5.7 cartridge is its high velocity. The round can reach velocities of up to 2,300 feet per second, which is significantly faster than most traditional pistol cartridges. This high velocity results in a flat trajectory, which means that the bullet will travel in a relatively straight line over long distances. This makes it easier to hit targets at longer ranges, which is particularly useful for law enforcement and military applications.

Another advantage of the 5.7 cartridge is its armor-piercing capabilities. The round is designed to penetrate body armor, which makes it an attractive option for law enforcement and military personnel who may encounter armored targets. The bullet is also designed to fragment upon impact, which can cause more damage to the target.

However, the 5.7 cartridge is not without its drawbacks. One of the main criticisms of the round is its relatively low stopping power. Because the bullet is small and lightweight, it may not be as effective at stopping an attacker as a larger, heavier bullet. This is particularly true when compared to traditional pistol cartridges like the .45 ACP or the 9mm.

Another potential drawback of the 5.7 cartridge is its cost. Because it is a relatively new and specialized round, it may be more expensive than more traditional pistol cartridges. This could make it less accessible for some shooters, particularly those who are on a tight budget.

So, what is the practical use of the 5.7 cartridge? The round is primarily used by law enforcement and military personnel who need a cartridge that can penetrate body armor and provide accurate shots at longer ranges. It is also used by some civilian shooters who appreciate its flat trajectory and low recoil.

In conclusion, the 5.7 cartridge is a unique and specialized round that offers some distinct advantages over more traditional pistol cartridges. Its high velocity and armor-piercing capabilities make it attractive for law enforcement and military applications, while its flat trajectory and low recoil make it useful for civilian shooters. However, its low stopping power and potential cost may make it less attractive for some shooters.
