Federal Premium 9mm 147gr HST 20rds (P9HST2S)  

Effective self-defense requires ammunition that provides consistent expansion, optimum penetration and superior terminal performance. And HST® delivers. That's why it's already the duty load of choice for law enforcement officers throughout the world. Its specially designed hollow point won't plug while passing through a variety of barriers, and the bullet jacket and core hold together to provide nearly 100 percent weight retention through even the toughest materials.
