The G9 Defense 45 ACP 117 grain External Hollow Point represents a distinct approach to defensive handgun ammunition: instead of relying on expansion, the EHP projectile uses fluted copper geometry to create cavitation through fluid dynamics. Chambered in 45 ACP and launching a 117-grain solid copper projectile at 1400 fps with 509 ft-lbs of muzzle energy, this load is built for barrier penetration and controlled depth in tissue. The External Hollow Point is a lead-free defensive round designed to maintain structural integrity through common barriers — windshields, drywall, vehicle sheet metal — without transferring energy prematurely, ensuring consistent terminal performance on the intended target.
Performance at a Glance
The EHP projectile is precision-machined from solid copper with a patented exterior shape that drives lateral energy transfer on contact with tissue. Because there is no jacket to separate, the bullet remains intact through intermediate barriers. The light-for-caliber 117-grain weight achieves higher velocity than traditional 230-grain loadings, reducing felt recoil and enabling faster shot-to-shot transitions. Brass cases with Boxer primers are reloadable and non-corrosive. Manufactured in the United States, this ammunition meets the definition of a defensive handgun cartridge: one that delivers energy where it is needed, stops quickly in tissue to prevent over-penetration, and functions reliably across a range of real-world conditions.

The fluted geometry creates a bursting-type entrance wound and large temporary cavity, while the light projectile weight delivers lower recoil impulse compared to heavier 45 ACP loads. Shooters looking for barrier-blind performance in a lead-free package will find the EHP design addresses both requirements.

Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Follow the four universal rules of firearms safety at all times: treat every firearm as if it is loaded, never point the muzzle at anything you are not willing to destroy, keep your finger off the trigger until you are on target and have made the decision to fire, and be certain of your target and what lies beyond it.
- Verify that your firearm is chambered for 45 ACP and that local and state laws permit possession and use of lead-free defensive ammunition before ordering.
- Store ammunition in factory packaging or a dedicated container, away from moisture, direct sunlight, and temperature extremes. Lead-free projectiles eliminate lead exposure during handling and range cleanup.
