The Winchester Defender S9MMPDB1 delivers consistent terminal performance through its bonded jacket hollow point design, engineered specifically for personal protection applications. This 147-grain subsonic load combines controlled expansion with deep penetration across barrier materials.
What Makes This Different
The bonded jacket construction prevents core separation during expansion, maintaining bullet integrity through intermediate barriers like drywall, plywood, and heavy clothing. Unlike standard jacketed hollow points that can fragment or fail to expand consistently, the Defender's bonded design ensures reliable performance. The 147-grain weight provides subsonic velocity from most barrel lengths, reducing muzzle flash and blast in low-light situations.Key Features
