Speer Gold Dot Personal Protection Handgun Bullets .40/10mm .400" 165 gr GDHP 100/ct

The Speer Gold Dot Personal Protection Handgun Bullets .40/10mm .400" 165 gr GDHP are purpose-built defensive rounds engineered for law enforcement and civilian self-defense applications. These hollow-point projectiles deliver consistent performance across both .40 S&W and 10mm platforms, making them a reliable choice for shooters who demand ammunition that functions predictably under pressure. With 100 rounds per box, this quantity supports both training regimens and duty-ready preparedness without excessive stockpiling.

Gold Dot technology features a proprietary bonded-core construction that locks the lead core to the copper jacket, preventing jacket-core separation during expansion and ensuring maximum weight retention downrange. The 165-grain projectile weight strikes a balance between velocity and stopping power, particularly in .40 S&W loadings where it achieves reliable expansion while maintaining controlled penetration depth—typically 12–18 inches in ballistic gelatin—matching FBI protocol standards. The .400" diameter and hollow-point geometry promote consistent mushrooming across a range of barrier conditions, from soft tissue to intermediate obstacles.

Law enforcement agencies and armed citizens relying on .40 S&W or 10mm platforms benefit from Gold Dot's track record of real-world performance and consistent quality control. Reloaders will find these bullets suitable for handload development, though factory-loaded ammunition is recommended for duty and defensive carry to ensure consistent ballistics. Chronograph testing and function verification through your specific firearm remain essential before relying on any defensive round for personal protection.
