FN 5.7×28


The 5.7x28mm (AKA: FN 5.7×28) is a Center Fire cartridge with a Bullet Diameter of 0.224 in” (5.69mm) that is primarily used in Pistols and Rifles. The 5.7x28mm originated in Belgium in 1991. The 5.7x28mm also has a case length of 1.13 in” (28.7mm) and an overall length of 1.71 in” (43.43mm).

Additional Cartridge Designations: PDW Cartridge


5.7x28mm is a PDW Cartridge originally developed for use in the FN P90 DPW and the FN Five-Seven pistol. The 5.7x28mm is widely used by many nations, developed, backed and recommended by NATO for Police and Military use, including within the U.S. Secret Service.

The 5.7x28mm PDW Cartridge, like that of its direct competitor the 4.6x30mm, is widely known to have armor piercing capabilities and is capable of pushing velocities of close to 3000fps with a light weight projectile. Although the 5.7x28mm PDW Cartridge is widely accepted by many, the 4.6x30mm cartridge has still been adopted by many within NATO, putting these two PDW Cartridges in direct competition with each other.

Much like the 6.5x25mm CBJ cartridge, the 5.7x28mm cartridge offers a variety of loadings for different circumstances or uses, although to a lesser extent. Some of the varieties of 5.7x28mm you may see would include the SS90 (Original Designation), SS190 (Second Gen), SS192 HP (Hollow Point), SS196 SR (Modern Hornady Load with V-Max Projectile), SS195LF (NATO aligned Military & Police use), SS197SR (Much like the SS195LF, but commercially available for civilian use). The most common loading for all variants uses a 40gr projectile, and many offer velocities above 2000fps.
