The Winchester S40SWPDB Defender delivers maximum stopping power through bonded jacket hollow point technology specifically engineered for personal protection scenarios. This premium 40 S&W ammunition combines controlled expansion with deep penetration to neutralize threats effectively.
What Makes This Different
The bonded jacket construction prevents core separation during expansion, maintaining bullet integrity through barriers like heavy clothing, wallboard, and auto glass. Unlike standard hollow points that can fragment or fail to expand consistently, the Defender's bonded design ensures reliable performance across varying impact velocities. The 165-grain projectile strikes the optimal balance between manageable recoil and terminal effectiveness in 40 S&W platforms.Key Features
