The Winchester PDX1 Defender series represents a critical advancement in self-defense ammunition, meticulously engineered for consistent terminal performance in high-stakes environments. This 40S&W loading is designed to meet and exceed the rigorous performance parameters established by the FBI test protocol, providing predictable and effective incapacitation.
Key Features
Terminal Performance Optimization
Each PDX1 Defender round is precision-engineered to maximize terminal ballistics. The projectile design facilitates consistent expansion to approximately 1.5 times its original diameter upon impact, ensuring comprehensive energy transfer and disruption within the target. This controlled expansion, coupled with reliable penetration, addresses critical requirements for effective self-defense.
Advanced Projectile Construction
The core of the PDX1 Defender’s performance lies in its proprietary bonding process. The copper jacket is permanently welded to the lead core, creating a robust, unitary projectile. This construction mitigates jacket-core separation, preserving projectile integrity through various barriers and ensuring deep, consistent penetration alongside reliable expansion. This structural integrity is paramount for predictable performance under diverse conditions.
