History of the 5.7x28mm Round

 

Development and Purpose

 

The origin of the 5.7x28mm cartridge traces back to the late 1980s. NATO put forward a request for a new pistol and submachine gun round to replace the 9x19mm Parabellum cartridge used by most Western militaries.

 

Belgian manufacturer FN Herstal took on this challenge. Its objective was to create a round with superior range, accuracy, and terminal performance compared to the 9mm NATO round. The new cartridge also needed to reliably penetrate modern body armor at extended distances.

 

In 1990, FN completed work on the 5.7x28mm cartridge. It was designed specifically for their new P90 personal defense weapon platform. The original 5.7mm SS90 round achieved a muzzle velocity of over 2,800 ft/s from the P90’s 10.4-inch barrel. Against soft body armor, it could penetrate Level IIIA protection out to 200 meters.

 

After further development, FN introduced the improved SS190 round, which it fired a heavier projectile at 2,350 ft/s from the P90 and also reliably fed from a pistol. This allowed FN to produce a companion sidearm, later designated the Five-seveN.

 

The company submitted the integrated system, consisting of the P90, Five-seveN handgun and 5.7x28mm SS190 ammunition, to NATO for military trials and potential adoption. However, competing entries prevented it from becoming standardized across all NATO forces at the time.

 

Adoption

 

Despite not attaining NATO-wide authorization, the effectiveness of the 5.7x28mm system led to its widespread adoption among military and law enforcement agencies globally.

 

The round rapidly gained esteem for its terminal effects from small, lightweight platforms. Its ability to defeat body armor also appealed to counter-terrorism and special forces units. As more nations and agencies acquired the FN P90 and Five-seveN firearms, the 5.7x28mm cartridge expanded in usage and aftermarket support.

 

Around 2010, the 5.7x28mm began emerging in the civilian shooting world. Firearms manufacturers recognized the round’s potential for self-defense and sporting applications. The availability of carbines like the PS90 and smaller concealed carry pistols chambered in 5.7x28mm furthered its popularity in the commercial market. What originated as an armor-piercing submachine gun cartridge developed an impressive following among civilian shooters drawn to its unique set of advantages.

 

5.7x28mm Performance & Why You Want It 

 

The intended purpose behind developing the 5.7x28mm cartridge was achieving superior ballistic performance compared to the 9x19mm NATO round. The 5.7mm design lives up to these expectations through several favorable characteristics:

 

Lower Recoil – Despite higher pressures, the 5.7mm generates roughly half the felt recoil of a 9mm load. This allows for quicker follow-up shots and faster target reacquisition. Muzzle rise is more easily controlled as well.

 

Higher Muzzle Velocity – The smaller caliber and narrower cartridge case enable greater case capacity for the same overall size as a 9mm Luger round. This shows in the 150 to 300 ft/s higher velocity attained by 5.7mm loads.

 

Flatter Trajectory – Greater velocity translates to an exceptionally flat trajectory curve out to 100 yards, making the 5.7mm more forgiving for accuracy at varying distances.

 

Superior Terminal Ballistics – Its lightweight projectile tumbles rapidly upon impact, yielding significant wound channels and vital tissue disruption.

 

For defensive and tactical purposes, the 5.7x28mm provides shooters with advantages in shot placement, target visibility, recoil mitigation and terminal effects. The round’s high velocity and accuracy also appeal to hunting and sport shooting enthusiasts.

 

The 5.7mm cartridge effectively balances rifle-like ballistic potential with firing from compact, concealable platforms. As more becomes understood about its capabilities, this innovative caliber will continue garnering interest across the shooting community.

 

Final Thoughts

 

The 5.7x28mm endured a rocky start, hampered by misconceptions and politics early on. Despite not attaining NATO-wide adoption, the cartridge and firearms designed for it demonstrated enough effectiveness to garner a global following in military, law enforcement, and civilian sectors over time.

 

What sets the 5.7x28mm apart is its ability to reach ballistic performance levels comparable to the 5.56x45mm rifle round from small concealed carry weapons. This combination of terminal effects, accuracy, and shootability drives its appeal for personal defense roles. At the same time, competitive and recreational shooters appreciate the flat shooting nature and low recoil which enable rapid, accurate follow-up shots on target.

 

While the main drawbacks of expensive ammunition and limited firearm options persist, continued manufacturing support has mitigated these issues today. The 5.7x28mm is experiencing a renaissance among  a receptive shooting community ready to embrace its advantages.
