It is designed to work and function in the many 380 micro pistols made today. A non-lead projectile with a Hollow Point Flat Based (HPFB) design. It`s OAL is 0.955” allowing it to function properly even though it is a hollow point. Due to velocity and pressure restraints, this bullet fragments into several pieces, penetrating 9-11” of gelatin.
