Federal Premium Personal Defense HST 9mm Luger +P 124 Grain Jacketed Hollow Point Nickel-Plated Cased Centerfire Pistol Ammo 20 Rounds. Federal Premium makes several different bullets in this caliber including jacketed hollow point FMJ and others. And all of them expand reliably through a variety of barriers so that you can more easily draw and fire the loaded rounds. What's more each caliber has specific ballistics that make them perform differently in the same way. For example 9mm +P = 124 gr HP. The special nose profile of these rounds provides you with reliable Federal brass and you'll get consistent expansion and accuracy from Federal Premium HST ammo. The loads' greater velocity gives you the energy you need for self-defense situations. And a unique Federal primer provides powerful ignition and consistent cycling in semi-automatic pistols.
