Speer® Gold Dot® Personal Protection Handgun Ammo has earned a solid reputation over the years as having one of the most effective bullets for law enforcement in the USA, as well as internationally. A 2-stage hollow-point cavity, with a pre-fluted core, expands dramatically to a pre-determined fault line, and then stops to control the final diameter. The copper bullet jacket is bonded to the lead core with Uni-Cor technology, one molecule at a time, resulting in ultimate weight retention after expansion. Nickel-plated brass cases resist corrosion and enhance reliable feeding and extraction. Speer engineers fine-tune each specific powder charge and bullet weight for maximum field performance.
