Introduction
The FN 5.7×28mm (designated as the 5.7×28 by the C.I.P. and FN 5.7x28mm NATO) is a small-caliber, high-velocity, smokeless-powder, rebated, bottleneck, centerfire cartridge designed for pistols and personal defense weapons (PDW) uses, manufactured by FN Herstal. It is similar in length to the .22 WMR and .22 Hornet. Unlike many new cartridges, it has no parent case; the complete package was developed from scratch by FN.
The 5.7×28mm was developed in conjunction with the FN P90 PDW and FN Five-seven pistol in response to NATO requests as a replacement for the 9×19mm Parabellum cartridge. In 2002 and 2003, NATO conducted a series of tests with the intention of standardizing a PDW cartridge as a replacement for the 9×19mm Parabellum cartridge. The tests compared the relative merits of the 5.7×28mm cartridge and the 4.6×30mm cartridge, which was created by Heckler & Koch as a competitor to the 5.7×28mm. The NATO group subsequently recommended the 5.7×28mm cartridge, citing superior performance in testing, but the German delegation objected and the standardization process was halted until 2021 when it was officially adopted as a NATO standard STANAG 4509.
By 2006, FN’s 5.7×28mm firearms—the P90 PDW and Five-seven pistol—were in service with military and police forces in over 40 nations throughout the world. In the United States, 5.7×28mm firearms are currently used by numerous law enforcement agencies, including the U.S. Secret Service.
In addition to being used in the FN P90 and FN Five-seven firearms, the 5.7×28mm cartridge has subsequently been used in a number of other weapons, such as the AR-57 and FN PS90 carbines. Excel Arms has developed four firearms chambered in 5.7×28mm, MasterPiece Arms offers three different firearms in 5.7×28mm., and CMMG offers several of its AR-Style Banshee firearms in 5.7×28. As of December 2019, Ruger offers its Ruger-57 semi-automatic pistol chambered in this cartridge. January 2021 saw the announcement by Kel-Tec of the P50 handgun, which uses 50-round P90 magazines. Palmetto State Armory introduced its Rock 5.7 pistol in January 2022; it became available for purchase in May 2022.
The 5.7×28mm cartridge itself is produced in a number of varieties, two of which—the SS195LF and SS197SR—are currently offered by FN to civilian shooters.
The 5.7×28mm cartridge was designed in response to NATO requests for a replacement for the 9×19mm Parabellum cartridge. According to the NATO requirement, the new cartridge was to have greater range, accuracy, and terminal performance than the 9×19mm cartridge. Additionally, it was to be capable of penetrating body armor. FN Herstal responded to the NATO requirement by developing the 5.7×28mm cartridge and two associated weapons: the FN P90 personal defense weapon (PDW) and the FN Five-seven pistol.
The original 5.7×28mm cartridge, called the SS90, was introduced in 1990. It used a 1.5 g (23 gr) plastic-core projectile, which was propelled at a muzzle velocity of roughly 850 m/s (2,800 ft/s; Mach 2.5) when fired from the P90. A United States patent application for the projectile design used in the SS90 was filed by FN’s Jean-Paul Denis and Marc Neuforge in 1989. U.S. Patent 5,012,743 (“High-Performance Projectile”) was received in 1991.
When fired from the FN P90, the 5.7×28mm SS190 can penetrate the NATO CRISAT vest or a Level IIIA Kevlar vest at a range of 200 m (219 yd).
The 5.7×28mm SS90 cartridge was discontinued and replaced, in 1993, with the 5.7×28mm SS190. The SS190 uses a 2.7 mm (0.11 in) shorter projectile with a mass of 2.0 g (31 gr), which has when fired from the P90, a muzzle velocity of roughly 716 m/s (2,350 ft/s; Mach 2.1). The shorter length of the SS190 projectile allows it to be more conveniently used in the 5.7×28mm FN Five-seven pistol, which was also being developed at that time.
In 1993, FN introduced a modified version of the P90 with a magazine adapted to use the SS190 cartridge. Several specialized 5.7×28mm varieties were also developed alongside the SS190, such as the L191 tracer round and the subsonic SB193 bullet for sound-suppressed use. The 5.7×28mm chambered FN Five-seven pistol then went into production in 1998.
In 2002 and 2003, NATO conducted a series of tests with the intention of standardizing a PDW cartridge as a replacement for the 9×19mm Parabellum. The tests compared the relative merits of the 5.7×28mm cartridge and the HK 4.6×30mm cartridge, which was created by German small arms manufacturer Heckler & Koch as a competitor to the 5.7×28mm. The results of the NATO tests were analyzed by a group formed of experts from Canada, France, the United Kingdom, and the United States, and the group’s conclusion was that the 5.7×28mm was “undoubtedly” the more efficient cartridge. Among other points, the NATO group cited superior effectiveness (27 percent greater) for the 5.7×28mm against unprotected targets and equal effectiveness against protected targets. It also cited less sensitivity to extreme temperatures for the 5.7×28mm and cited a greater potential risk of barrel erosion with the 4.6×30mm. In addition, the group pointed out that 5.7×28mm is close to the 5.56×45mm NATO by its design and manufacture process, allowing it to be manufactured on existing production lines. The group also noted that 5.7×28mm firearms had existed for a longer period of time than 4.6×30mm firearms, and that the 5.7×28mm FN Five-seven pistol was already in production at that time, while the 4.6×30mm Heckler & Koch UCP pistol was a new concept.
However, the German delegation and others rejected the NATO recommendation that 5.7×28mm be standardized, halting the standardization process indefinitely. As a result, both the 4.6×30mm and 5.7×28mm cartridges (and the associated weapons) have been independently adopted by various NATO countries, according to preference; both the P90 and Five-seven are currently in service with military and police forces in over 40 nations throughout the world.
