History of the 5.7x28mm: Why was it developed?

Imagine if James Bond had a hand in designing a new cartridge for NATO's elite forces. That's exactly how the 5.7x28mm cartridge came to be. It was a response to NATO's request for a replacement to the popular 9x19mm Parabellum cartridge, but with even greater range, accuracy, and terminal performance, as well as the ability to penetrate body armor. Enter FN Herstal, who not only met but exceeded NATO's requirements by developing not one, but two weapons to fire the new cartridge - the iconic FN P90 personal defense weapon and the sleek FN Five-seven pistol.

The original version of the 5.7x28mm cartridge, known as the SS90, was introduced in 1990 and featured a plastic-core projectile that could reach muzzle velocities of up to 2,800 ft/s when fired from the P90. A patent for the projectile design was filed by FN's Jean-Paul Denis and Marc Neuforge in 1989, and the High-Performance Projectile patent was awarded in 1991.

By 1993, FN had replaced the SS90 with the improved SS190 cartridge, featuring a shorter projectile that weighed in at 2.0 g (31 gr) and reached muzzle velocities of 2,340 ft/s when fired from the P90. This allowed the SS190 to be used more conveniently in the FN Five-seven pistol, which went into production in 1998.

But that's not all - FN also developed specialized 5.7x28mm rounds like the L191 tracer round and the subsonic SB193 bullet for sound-suppressed use. And if you're wondering just how powerful this cartridge really is, when fired from the P90, the SS190 can even penetrate a NATO CRISAT vest or a Level IIIA Kevlar vest at a range of 200 m. That's some serious firepower packed into a sleek, lightweight package.

5.7x28mm NATO Testing and Controversy: 5.7x28mm vs 4.6x30mm

Are you ready for a showdown between two of the most powerful cartridges in the world? Let's talk about the infamous lawsuit filed by HK regarding the 5.7x28mm cartridge, and why it has caused such a stir in the world of firearms.

In 2002 and 2003, NATO conducted a series of tests to find a replacement for the 9x19mm Parabellum cartridge. The tests compared the 5.7x28mm cartridge to the HK 4.6x30mm cartridge, created by the German small arms manufacturer Heckler & Koch. The results of the tests were analyzed by a group of experts from Canada, France, the United Kingdom, and the United States, who concluded that the 5.7x28mm was the more efficient cartridge by a long shot.

The NATO group cited a number of reasons for their decision, including the 5.7x28mm's superior effectiveness against unprotected targets (27 percent greater than the HK cartridge), its equal effectiveness against protected targets, and its lower sensitivity to extreme temperatures. They also noted that the 5.7x28mm was easier to manufacture and had a lower risk of barrel erosion than the HK cartridge. Plus, the 5.7x28mm was already in production with the FN Five-seven pistol, while the HK UCP pistol was still a new concept.

However, not everyone was on board with the NATO recommendation. The German delegation and others rejected the idea of standardizing the 5.7x28mm, and the standardization process was halted indefinitely. As a result, both the 4.6x30mm and 5.7x28mm cartridges have been independently adopted by various NATO countries, depending on their preferences.

But here's the kicker: despite the controversy, there's no denying that the 5.7x28mm is a superior cartridge in many ways. Its design and manufacturing process is similar to the 5.56x45mm NATO cartridge, making it easy to produce on existing production lines. And with its proven track record and widespread adoption, it's clear that the 5.7x28mm is a force to be reckoned with in the world of firearms.

5.7x28mm vs 4.6x30mm present day [2023]

For the past 20 years, law enforcement agencies and elite military units have been using both the 4.6x30mm and 5.7x28mm cartridges during the war on terror. But the debate on which cartridge is superior has raged on until recently. Enter Doc, a former Army Special Forces 18D medical sergeant who has served time in the world's most elite military unit, CAG, also known as Delta Force.

One day, while Doc and I were doing some training in a shoothouse, I noticed he was wearing an FN hat. I jokingly asked him if he had a gig with FN now, to which he replied, "No. I just really like their machine guns." We bantered back and forth about the effectiveness of various weapons until I brought up the H&K MP7 and the 4.6x30mm. But Doc's response was clear: he thought they were trash. He even recounted a story of how it took a full magazine from his MP7 to take down a local terrorist overseas who was shooting at him with a Makarov.

So, what cartridge does Doc prefer? The 5.7x28mm, hands down. And it seems NATO agrees with him! After nearly 20 years of objections from the German delegation, NATO finally adopted the 5.7x28mm as an official cartridge in 2021. And with superior effectiveness against unprotected targets, less sensitivity to extreme temperatures, and greater potential for manufacture on existing production lines, it's no wonder why the 5.7x28mm came out on top.

So there you have it, folks. The controversy has finally been put to rest, and the 5.7x28mm reigns supreme. But who knows what the future holds for new cartridges and weapons? One thing is for sure, though - Doc will be ready to put them to the test.

Are you ready to learn about a cartridge that's been gaining popularity among gun enthusiasts, military personnel, and law enforcement? Look no further than the 5.7x28mm cartridge, a unique and fascinating round that has been used in both military and civilian applications around the world. Its compact size, high velocity, and low recoil make it a favorite among those who use it. In this discussion, we'll dive into the design and capabilities of this powerful cartridge, explore its various uses in different settings, and highlight some of the top ammunition manufacturers producing it. Trust us, after learning about the 5.7x28mm, you'll be wondering why you don't already own it.

5.7x28mm Cartridge Design

One of the many reasons that set this cartridge apart is its lightweight construction and small diameter, allowing for extra ammunition to be carried without adding significant weight or bulk. Plus, its high-velocity results in an exceptionally flat trajectory, making it a favorite among accuracy enthusiasts that love to hose down B8s at the range.

One of the most impressive features of the 5.7×28mm cartridge is its ability to penetrate Kevlar protective vests, making it a popular choice among military and law enforcement personnel. However, it's important to note that sporting variants of the cartridge are classified as not armor-piercing by the U.S. Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF).

The projectile design of the 5.7×28mm also limits overpenetration and risk of ricochet, making it a safer option for certain applications. And unlike conventional pistol bullets, the lightweight projectile loses much of its kinetic energy after traveling only 400 meters, reducing the risk of collateral damage.

When it comes to design features that enhance the reliability of the firearm the 5.7 will not disappoint.  The 5.7×28mm cartridge by FN Herstal boasts design features that enhance its reliability and functionality. For instance, the cartridge cases are coated with a special polymer material that makes it easier to extract from the PS90 carbine, thanks to the high chamber pressures and lack of case tapering. This polymer coating also ensures proper feeding and functioning of the rounds in magazines, making it an ideal cartridge for both military and civilian applications. These features, combined with the cartridge's other advantages like low recoil, flat trajectory, and reduced risk of over-penetration, make the 5.7×28mm an impressive cartridge that's worth exploring further.

Overall, the 5.7×28mm cartridge is a unique and versatile option for firearms enthusiasts, with its impressive capabilities and design features. It's no wonder why so many more manufacturers have developed firearms chambered in this cartridge in recent years.  


5.7x28mm Ammunition Types and Manufacturers: Who makes 5.7 Ammo?

FN 5.7x28mm Ammunition

Image from; The Armory


  1. SS90 Prototype Cartridge: The SS90 was an initial experimental round exclusively used in the earliest models of the P90 firearm. It utilized a lightweight 1.5-gram (23-grain) full metal jacket bullet with a polymer core, achieving a muzzle velocity of approximately 850 meters per second (2,800 feet per second). However, the SS90 was discontinued in 1994, and replaced by the heavier and shorter 2.7mm (0.11 inch) SS190 projectile.


  1. SS190: The SS190 FMJ was introduced in 1993 as an improvement over the SS90. It provided better performance than its prototype counterpart and was slightly shorter in length, making it more convenient for use in the Five-seven pistol that was also in development at the time. When fired from the P90, the SS190 propels a 2.0-gram (31-grain) bullet with a steel penetrator and an aluminum core at a muzzle velocity of around 715 meters per second (2,350 feet per second). The SS190 is available in plain, black, and black-on-white tip colors and is classified as armor-piercing (AP) handgun ammunition by the ATF, with its sale limited to military and law enforcement customers by FN.

When tested by the Houston Police Department SWAT, the SS190 fired from the P90 into bare ballistic gelatin exhibited penetration depths ranging from 28 to 34 centimeters (11 to 13.5 inches). In a 1999 test by the Royal Canadian Mounted Police (RCMP), the SS190 fired from the P90 at a distance of 25 meters (27 yards) showed an average penetration depth of 25 centimeters (9.85 inches) after penetrating level II body armor.  

  1. L191 Tracer Ammunition: The L191, previously known as the SS191, is a tracer cartridge designed to aid in spotting the bullet in low-light conditions. The L191 projectile contains combustible chemicals at its rear, producing a visible light trail that extends up to 200 meters (219 yards). It is available with red and red-on-black tips. Despite having the same performance and trajectory as the SS190, the L191 is classified by the ATF as armor-piercing handgun ammunition, and FN restricts its sale to military and law enforcement customers.
  2. SS192: The SS192 cartridge was taken out of production in late 2004. It featured a 1.8-gram (28-grain) hollow point bullet, complete with a copper jacket and an aluminum core. The bullet had a length of 21.6 millimeters (.85 inches) and an unmarked hollow nose with a 7.6-millimeter (0.3-inch) depth and a 0.8-millimeter (0.03-inch) opening. Despite its impressive specifications, the SS192 was not classified as armor-piercing by the ATF. In fact, testing conducted by FNH USA showed that it failed to penetrate a Level IIIA vest when fired from the Five-seven firearm.
  3. SB193 Subsonic 5.7x28mm: The SB193 cartridge, also previously known as the SS193, features a Sierra Game King FMJBT (FMJ boat tail) projectile weighing 3.6 grams (55 grains). As a subsonic cartridge, it lacks the supersonic "crack" that accompanies faster rounds. Additionally, when paired with a suppressor, the muzzle report is considerably reduced. The reduced muzzle velocity of the SB193 leads to a slight reduction in recoil force of 1.3 kgm/s. The SB193 cartridge is identified by its white tip color and is only sold to military and law enforcement customers by FN.
  4. T194 5.7 Training Round: In 2002, the T194 training round was taken out of production. The T194 can be seen as a precursor to the SS192 or SS195 as it had the same copper-jacketed aluminum core bullet weighing 1.8 g (28 grain) and was propelled at the same muzzle velocity. The tip of the T194 was colored green.
  5. SS195LF: The SS195LF is a type of ammunition that is available for commercial use. It is designed to replace the SS192 round, which was discontinued in late 2004. Like the SS192, the SS195LF features a 1.8-g (28 grain) copper-jacketed aluminum core bullet and has similar ballistics. The SS195LF is distinguished by its unmarked, hollow void at the tip and silver-colored primer. It is classified by the ATF as non-armor piercing and is currently manufactured by FN Herstal in Belgium. Another notable feature of the SS195LF is that it features a lead-free primer.
  6. SS196SR: The SS196SR cartridge was introduced in 2005 but has since been replaced by the SS197SR.  It utilized a 2.6-g (40 grain) Hornady V-Max bullet with a lead core that was capable of reaching a muzzle velocity of approximately 500 m/s (1,650 ft/s) when fired from the Five-seven.The V-Max bullet's polycarbonate tip was designed to expand the bullet upon impact. The SS196 was classified as not armor-piercing by the ATF and was found to be unable to penetrate a Level II vest when fired from the Five-seven in FNH USA testing. It could be recognized by its red polymer tip.
  7. SS197SR: The SS197SR, which is loaded for a higher muzzle velocity than the SS195LF, is now available to civilian shooters in addition to the SS195LF. Both rounds use the same 2.6-g (40 grain) Hornady V-Max projectile with a lead core. The SS197SR features a blue-colored polymer tip instead of the red tip found on the SS196 projectile. Since 2006, Fiocchi has produced the SS197 for FN Herstal under contract, and it is currently distributed in the United States by Federal Cartridge Company.

5.7 vs 9mm? Which is better? 


The 5.7x28mm and 9mm are both popular rounds in the firearm industry, but they have their differences. 5.7 firearms tend to have a greater capacity and lighter recoil, and can even penetrate armor. However, the 9mm is typically less expensive and has a wider range of ammunition options. When it comes down to it, the choice between the two depends on personal preference and intended use. For self-defense purposes, the 5.7 may be a better choice due to its armor-piercing capabilities, while the 9mm may be a more practical choice for target shooting due to its lower cost and a wider range of ammunition options. Ultimately, both rounds are effective and have their own unique advantages and disadvantages.
