Overview of 5.7x28mm Ammo

The 5.7x28mm cartridge was introduced in 1991 by Belgian company FN Herstal to replace the 9x19mm cartridge. It was designed to offer level IIIA body armor piercing capabilities at 200 meters.

Thanks to its bullet shape, it also reduces the risk of ricocheting, so shooters and law enforcement agencies can have a little more confidence in this compact, accurate, low-recoil round.

  • Longshooter said:

    Gang. This is SUBsonic ammo - of *course* it isn't going to feed reliably in a pistol or rifle unless is equipped with a suppressor. Please, read up - it isn't expected to! Without the suppressor, which provides substantially more back pressure to the action when the round is fired, your gun WILL NOT CYCLE. Use **ONLY w/ a suppressor** (what virttually all subsonic ammo is literally is designed for.)

  • Lyle said:

    Generally, I like Fiocchi ammo, however the 62 grain subsonic 5.7 x 28 constantly misfeeds in both my S&W 5.7 x 28 and my Ruger 57. I have no issues with the Fiocchi 40 grain hollow point.

  • Scott said:

    The ammo did not perform well at all! The magazine hold 22 rounds, rack the slide tire round went off would not eject properly had to rack the gun every time to fire next round! Very disappointing after spending hundreds and the ammo doesn’t work properly or preform as expected!
