Both standard and +P Underwood Extreme Defender 68gr .380 ACP rounds performed well, penetrating over 12 inches of gel after passing through denim. The +P load achieved deeper penetration (15-15.5 inches) and a larger wound cavity than the standard pressure load (12.25-12.5 inches).

What firearm was used for the .380 ACP gel test?

The test utilized a Ruger LCP Max pistol, which features a 2.75-inch barrel. While not officially +P rated, the host successfully fired +P ammunition through it, noting slightly lower velocities due to the short barrel.

What makes the Underwood Extreme Defender bullet design unique?

The Extreme Defender features a fluted copper projectile designed for fluid disruption, similar to hollow points, but without needing expansion. This design aims for 'barrier blind' performance against materials like denim or bone.

Did the Underwood Extreme Defender bullets expand in the gel test?

No, the recovered Underwood Extreme Defender bullets showed no deformation and maintained their original fluted copper shape. This indicates their effectiveness relies on their design rather than expansion.
