The Winchester S357SPDB Defender delivers maximum stopping power for law enforcement and personal protection applications. This 357 SIG ammunition features bonded jacket hollow point construction that ensures reliable expansion and weight retention upon impact.
What Makes This Different
The bonded jacket design prevents core-jacket separation during expansion, maintaining bullet integrity through barriers like heavy clothing, wallboard, and auto glass. Standard hollow point rounds often fragment or fail to expand consistently, while the Defender's bonded construction maintains 95% weight retention. This translates to deeper penetration with controlled expansion, meeting FBI protocol standards for duty ammunition.Key Features
