High Performance Built for Self Defense

This load is engineered as high performance self defense ammo from the ground up, not a repurposed target round. Underwood tests each loading with real firearms under real-world conditions rather than relying solely on lab pressure barrels, which is what gives this ammunition its reputation for field tested handgun stopping power among 45 GAP shooters who carry for protection.

Consistent Expansion You Can Trust

The 230 grain hollow point is built for consistent 230 grain expansion across a range of barrier and clothing scenarios, with a jacket-to-core bond that resists fragmentation and helps the bullet reach adequate penetration depth. That performance, paired with trusted Underwood ammunition quality and hand-inspected brass, makes this a dependable option for a 45 GAP defensive pistol.
