FIOCCHI HP 5.7X28MM 35GR JF 50/500

Description

Fiocchi’s Hyperformance Defense load in 5.7x28mm is built for shooters who carry or home-defend with a modern 5.7-chambered pistol and want ammunition that actually leverages what the platform was designed to do. The 5.7x28mm cartridge earns its reputation from speed, and this load feeds that strength: at 1,700 feet per second, the 35-grain projectile stays flat across typical defensive distances and arrives with enough velocity for the jacketed frangible construction to do its job cleanly.

The jacketed frangible bullet design matters here. On a hard surface—a wall stud, concrete, steel—a frangible projectile breaks apart rather than ricocheting as a single mass, which is a meaningful consideration in a home-defense context. Against soft tissue it behaves differently, delivering energy transfer through controlled fragmentation rather than the deep, narrow channel of a conventional hollow point. This makes it a different trade-off than a bonded defensive round, not a better or worse one—the right choice depends on what a shooter prioritizes between penetration depth and fragmentation behavior.

At 35 grains, this is a light projectile even by 5.7x28mm standards, and that contributes directly to the cartridge’s characteristically low recoil. For shooters running a platform like the FN Five-seveN or the Ruger-57, that translates to faster split times and easier target reacquisition under stress. Fiocchi loads this in boxer-primed brass, consistent with their centerfire pistol line, and the 50-round pack makes it practical for working through a defensive evaluation without committing to a full case. Each round is manufactured to the same dimensional and pressure standards that keep modern 5.7 pistols running reliably—feeding and cycling are not afterthoughts in a defensive load.
