Speer's original Gold Dot line remains a benchmark for both self-defense and duty use, and it's earned the trust of law enforcement world-wide. It features a pressure-formed lead core that's bonded to an extremely uniform jacket a single atom at a time. This virtually eliminates separation on impact for more retained weight and penetration to crucial depths. Its Gold Dot hollow-point design expands consistently through the full range of barriers. Ignition and cycling are guaranteed thanks to sealed primers and nickel-plated brass.
