5.7x28mm ammo is one of the fastest centerfire cartridges available. Its high muzzle velocity has made it popular among law enforcement and military agencies. Despite its small size, this round is adequate for self defense. There are different types of 5.7x28 ammo, each of which is used for a specific purpose. Listed below are some of the main differences between these cartridge types.
The 5.7x28mm cartridge was originally designed as a small, high-velocity centerfire cartridge for the PDW (Personal Defense Weapon). The PDW is a modern class of firearm not a submachine gun or a rifle. While the PDW was originally intended to replace the 9mm cartridge in NATO service, it was released onto the commercial market in 1989. Several years later, the round became popular and is still in service.
The 5.7mm round is most common for home defense and personal defense firearms. It is an excellent choice for self defense, as it offers a high penetration capacity. The best 5.7x28 ammo for concealed carry handguns is a hollow point. Speer Gold Dot hollow points are superior to other commercially available rounds, as they provide higher penetration and expansion. These hollow points are more reliable and are a better choice than their counterparts.
The 5.7x28mm rounds have slightly less recoil than the 9mm, so they're more effective at longer ranges. They don't fall below your point of aim until close to 150 meters. It's not so much about power as it is about increased magazine capacity and penetrative ability. The main advantages of 5.7x28mm rounds are:
The 5.7x28mm cartridge is used in a number of weapons. The PS90 pistol, the PS90 for civilians, and the FN PS90 carbines are all chambered in this caliber. In the United States, several manufacturers of firearms using the 5.7x28mm cartridge have come out with versions. In addition, FN Herstal has introduced a new weapon system, the FN P90, first used by Belgian special forces in 1991. Today, over forty countries use this weapon system. Its unique feeding system allows users to load fifty rounds into a magazine located on top of the receiver.
While the 5.7x28mm round is marketed as a blisteringly fast cartridge, it's not the fastest. It's been around long enough to have a wide range of bullet weights and velocities. This makes it a popular choice for target shooting and self-defense. Despite being small, the round is effective at crushing tissue on its way to target. The 5.7x28mm projectile is only slightly slower than its corresponding 9mm round.
In the early 1970s, NATO requested that the 5.7x28mm round be developed as a replacement for the 9mm cartridge. In response, FN produced the Five-seveN pistol and the P90 personal defense weapon. Ruger-57 was the first handgun model to be designed to use 5.7x28mm ammo. Eventually, Heckler & Koch and other manufacturers began to develop the 4.6x30mm cartridge, which were both rejected by NATO.
