The Speer Gold Dot Handgun Ammo in 40 S&W, 180 gr hollow point brings law-enforcement-proven performance to your home and personal defense arsenal, and when I walk customers through the Gold Dot series I point out its reputation for consistent penetration and controlled expansion through common barriers so you can expect reliable terminal performance when it matters most. This Speer 40 S&W load launches a 180-grain hollow point at about 1025 fps for roughly 420 ft-lbs of energy, uses nickel-plated brass casings for feeding reliability and corrosion resistance, and carries the trust of officers and range professionals across the United States. If you carry or keep a pistol for home defense, this ammunition is tailored to provide predictable wound profiles and accuracy from duty-sized barrels while minimizing over-penetration risk compared with full metal jacket rounds. For range practice that mirrors defensive ballistics, or for building confidence with your 40 S&W defensive platform, these Gold Dot rounds deliver consistent performance, dependable feeding, and the law-enforcement pedigree shooters look for in premium self-defense ammunition.
