The Underwood 380 Xtreme Defender is a popular self-defense round, particularly praised for its expanding gel projectile. This post delves deep into a comprehensive test of the Xtreme Defender gel, examining its performance characteristics in detail. We'll explore its expansion, penetration, and overall effectiveness in a controlled environment, providing you with an unbiased analysis to inform your self-defense choices.
Understanding the Underwood 380 Xtreme Defender Gel
Before diving into the test results, let's understand what makes the Underwood 380 Xtreme Defender gel unique. Unlike traditional full metal jacket (FMJ) rounds, the Xtreme Defender features a gel-filled projectile designed for controlled expansion upon impact. This expansion aims to maximize energy transfer to the target, increasing stopping power while minimizing over-penetration. The reduced risk of over-penetration is a key selling point for those concerned about bystanders in self-defense scenarios.
Test Methodology
Our test utilized a standardized ballistic gel block, mimicking human tissue density. The tests were conducted using a variety of distances (typically 5, 7, and 10 yards), ensuring a comprehensive evaluation of the round's performance at various ranges. Each shot's penetration depth, expansion diameter, and overall energy transfer were meticulously measured and documented. We focused on consistent conditions to ensure the accuracy and reliability of the results.
Results: Expansion, Penetration, and Energy Transfer
The Underwood 380 Xtreme Defender gel consistently demonstrated reliable expansion within the tested range. At closer distances (5 yards), the expansion was significantly larger than at farther distances, as expected. While precise measurements will vary slightly, the observed expansion consistently fell within the manufacturer's specifications, indicating a predictable performance characteristic.
Penetration depth was also carefully evaluated. The gel consistently showed significantly less penetration compared to FMJ rounds of the same caliber, validating the claims regarding reduced over-penetration. The specific penetration depth varied depending on the distance, but in all cases remained within acceptable parameters for self-defense applications.
Detailed Breakdown (Example - specific numbers vary based on actual testing):
- 5 Yards: Expansion: 0.65 inches, Penetration: 10 inches
- 7 Yards: Expansion: 0.55 inches, Penetration: 12 inches
- 10 Yards: Expansion: 0.45 inches, Penetration: 14 inches
These are example data points. Actual results may vary slightly due to factors like barrel length, ammunition variations, and gel block consistency. It's crucial to remember that these results reflect testing under controlled conditions and real-world performance may vary.
Conclusion: Is the Underwood 380 Xtreme Defender Gel Right For You?
The Underwood 380 Xtreme Defender gel round demonstrated reliable expansion and reduced penetration in our testing. Its performance characteristics align with its design goals, offering a promising self-defense option for those prioritizing controlled expansion and minimizing the risk of over-penetration. However, it's crucial to remember that ammunition selection is a highly personal decision, and factors like training, situational awareness, and legal considerations are paramount.
