Description

.357 Sig 125gr DPX – Barrier-Blind Defense with Every Shot

The COR®BON .357 Sig 125gr DPX is engineered for real-world defensive situations where standard hollow points fall short. When threats are hiding behind glass, steel, or dense material, this solid copper load delivers reliable penetration, consistent expansion, and maximum weight retention.

Unlike jacketed bullets that may fragment or deflect, the .357 Sig 125gr DPX uses a homogenous copper design that stays intact on impact. This bullet doesn’t just punch through barriers—it performs once it gets past them. Internal serrations allow it to expand rapidly into six sharp petals, doubling the diameter for devastating terminal damage.

Because of its 100% copper construction, this round remains legal in jurisdictions with lead-free requirements, such as California. It also burns cleaner, reducing fouling in your firearm. From a 4-inch test barrel, it hits 1350 feet per second and generates 505 foot-pounds of muzzle energy—power that translates into real stopping force.

COR®BON developed this load using FBI-standard testing protocols. Even after penetrating four layers of heavy denim, the bullet consistently achieves 12″–18″ of soft tissue penetration. More importantly, it retains 100% of its original weight and delivers a massive permanent wound cavity.

Whether you’re on duty or carrying concealed, the .357 Sig 125gr DPX provides the confidence you need when failure isn’t an option. It feeds smoothly, hits hard, and performs through the toughest conditions.
